Configure PrizmDoc Server using the services Central Configuration file. The configuration file will perform environment variable expansion in path values. The environment variable must be contained within a quoted string and enclosed with the % character. In most cases of Windows and Docker paths, single-quoted strings can be used which don't require any escaping. If you prefer using double-quoted strings, make sure to escape the Windows paths separator \ and other special characters.

For example, "%ALLUSERSPROFILE%" or "%my_path%/subpath" are both valid paths containing environment variables which will be expanded at runtime.

NOTE: PrizmDoc Cloud uses specific default values that differ from the self-hosted default values as noted in the PrizmDoc Cloud Default Values section below.

Working with the Central Configuration File

The locations for the Central Configuration file are:
- Windows: C:\Prizm\prizm-services-config.yml (given the default installation directory)
- Docker: <config_folder>/prizm-services-config.yml, where <config_folder> is the folder that you mapped as /config when creating the container. See Installing / Using Docker for more details.
- Kubernetes: configuration parameters are provided via a ConfigMap resource. See Deployment to Kubernetes Guidance for more details.
After making any changes to the configuration files, you need to restart the PrizmDoc Server.

IMPORTANT: Any time you make a change to the configuration files that affects document output, you must clear your cache.

Cache

`cache.directory`

Directory where cache data is stored.

Supported Values: Any valid path to a directory with read and write permissions.

Default Value: Windows: <install_dir>\cache; Docker: /data/cache

For example:

Windows: C:\Prizm\cache
Docker: /data/cache

Paths that contain environment variables must be quoted. When using double quotes, escape the backslashes:

'%ALLUSERSPROFILE%\Accusoft\Prizm\cache'
"%ALLUSERSPROFILE%\\Accusoft\\Prizm\\cache"

NOTE: When using PrizmDoc Docker containers, we recommend that you keep this property unchanged.

Central Database

NOTE: Use of a Central Database for PrizmDoc will be required in a future release in order to move towards eliminating server affinity.

The use of a Central Database is required in the following cases:

When using an Offline Metered License.
When the "v3" Viewing Packages API is turned on. DEPRECATION NOTICE: The "v3" viewing packages REST APIs have been deprecated and will be removed in a future release.

This feature is disabled by default. When the features listed above are not used, PrizmDoc Server will not use a database, or even check for its existence in the configuration.

`database.connectionString`

Connection string to the central database. MySQL is the only database currently supported. A MySQL example:

"mysql://prizm-user:password@prizm-server.database.host:3306/prizmdoc_server_db"

Supported Values: N/A

Default Value: ""

Environment Options

`eps.env`

Supported Values: Any string value

Default Value: ""

Fidelity

`fidelity.htmlRendering.externalContent.connectionTimeout`

Timeout for establishing a connection when downloading external content in HTML documents and HTML bodies of email documents, such as external images or CSS stylesheets.

Setting this parameter to a smaller value will allow faster rendering of HTML when external content is not available.

Supported Values: Must be an integer, followed by "ms" or "s". The suffixes stand for millisecond or second, respectively. There should not be any space characters between the number and suffix.

Default Value: 10s

`fidelity.msOfficeCluster.host`

This value is used to enable Microsoft Office Conversion connectivity when using the PrizmDoc Server Docker container. If needed, set this parameter to the hostname (or the IP) of a single PrizmDoc Windows server (or a load balancer of a cluster running on Windows) to utilize the Microsoft Office Conversion service running on Windows to have native rendering of Microsoft documents in PrizmDoc.

Supported Values: A valid IP address or hostname

Default Value: ""

`fidelity.msOfficeCluster.port`

This value is used to enable Microsoft Office Conversion connectivity when using the PrizmDoc Server Docker container. If needed, set this parameter to the public port of a single PrizmDoc Windows server (or a load balancer of a cluster running on Windows) to utilize the Microsoft Office Conversion service running on Windows to have native rendering of Microsoft documents in PrizmDoc. To connect to a single server or load balancer specify network.publicPort parameter of the remote server.

Supported Values: Any open HTTP port on the server

Default Value: 0

`fidelity.msOfficeCluster.scheme`

This value is used to enable encrypted communication between PrizmDoc servers running in Docker and PrizmDoc servers providing the native rendering of Microsoft documents.

When set to http, PrizmDoc uses the HTTP scheme for connecting to the PrizmDoc MSO server or cluster.

When set to https, PrizmDoc uses the HTTPS scheme for connecting to the PrizmDoc MSO server or cluster.

NOTE: You will also need to enable HTTPS support on your MSO server(s). See Security Guidance for more details.

Supported Values: One of the following strings: http, https

Default Value: http

`fidelity.msOfficeDocumentsRenderer`

Specifies the renderer to use with Microsoft Office documents.

When set to auto, PrizmDoc decides which renderer to use based on the MSO feature license state. If the MSO feature is present, then the Microsoft Office renderer will be used. Otherwise, LibreOffice will be used.

When set to libreoffice, PrizmDoc will use the LibreOffice renderer. If you are intending to use the LibreOffice renderer permanently, contact info@accusoft.com to obtain a metered license or a license with the MSO feature disabled.

When set to msoffice, PrizmDoc will use the Microsoft Office renderer if the MSO feature is enabled in the license key, otherwise a licensing error will be reported.

The parameter affects only Microsoft Office documents, RTF, and CSV files. Other documents will continue to be rendered with LibreOffice. For a complete list of supported file types see Supported File Formats.

NOTE: For PrizmDoc Cloud, the default value for fidelity.msOfficeDocumentsRenderer is msoffice.

Supported Values: One of the following strings: auto, libreoffice, or msoffice

Default Value: auto

`fidelity.svgMaxImageSize`

For source documents which contain images, ensures that the images in the SVG delivered to the browser do not exceed a particular pixel width and/or height. For example, a value of 8000 would ensure that any images in a PDF whose width or height were greater than 8000 pixels would be down-sampled before the image was added to the final SVG. A typical value is 8000. The default value for this property is configurable. The out-of-box configuration uses a default value of 8000. Use 0 to disable the optimization.

NOTE: When embedded images are very large and the optimization is disabled, browsers may display a placeholder icon instead of an image. If you want to keep high resolution images, consider setting this parameter to a large value, such as 30000, instead of setting it to 0.

Supported Values: Any integer greater than 0

Default Value: 8000

`fidelity.vectorBackgroundColor.view.default`

Defines the background color for viewing CAD documents if the background is not specified in the document. Also defines the background color for converting CAD documents to SVG, PNG, JPEG, and TIFF. DGN documents define their own background color, so this property does not affect them. Use fidelity.vectorBackgroundColor.view.override to define the background color (and ignore the background color specified in the document).

Supported Values: CSS color name, e.g., gray, or a hex RGB value, e.g., #FFFFFF

Default Value: white (#FFFFFF)

`fidelity.vectorBackgroundColor.view.override`

Defines the background color for viewing CAD documents, ignoring the background specified in the document. Also defines the background color for converting CAD documents to SVG, PNG, JPEG and TIFF, ignoring the background specified in the document. Overrides fidelity.vectorBackgroundColor.view.default.

Supported Values: CSS color name, e.g., gray, or a hex RGB value, e.g., #FFFFFF, or none

Default Value: none

`fidelity.vectorTolerance`

For CAD documents, controls how much path simplification is allowed. The path simplification algorithm will merge points which are "close together" to create an optimized SVG. You can think of this value as defining what "close together" means. A typical value is 0.3. Higher values introduce more simplification, but also more distortion. The value cannot be greater than 10.0. The default value for this property is configurable. The out-of-box configuration uses a default value of 0.3. Use 0 to disable the optimization.

Supported Values: A positive floating point value with a minimum value of 0.0 and a maximum value of 10.0

Default Value: 0.3

File Types

`__experimental.fileTypes.email.renderMeetingInfo`

Controls whether email headers containing the meeting information (When, Who) should be rendered in email documents.

NOTE: If you change the __experimental.fileTypes.email.renderMeetingInfo setting, you must clear your cache in order for the new settings to take effect on the files that were previously converted with the old rendering mode.

NOTE: This setting affects the rendering layout of email documents. Markup generated for documents rendered with this setting turned off cannot not be used for documents rendered with this setting turned on and vice versa.

Supported Values: true, false

Default Value: false

`fileTypes.email.dateFormat`

Specifies the format for the rendering of dates in email headers.

NOTE: This parameter will be ignored if the __experimental.fileTypes.email.renderMeetingInfo parameter is set to true.

The Sent header value will be composed by concatenating the message's sent date, time and time zone, separated by whitespaces. If fileTypes.email.dateFormat is an empty string, the date will not be displayed as part of the Sent header value.

See Configure Date and Time Headers in Email Documents for additional details.

Supported Values: Must be a string containing zero or more of the following substitution patterns:

yy: two digit representation of the year
yyyy: four digit representation of the year
M: one or two digit number of the month in year, not zero padded

MMM: name of the month in year, abbreviated to three letters
MMMM: name of the month in year, not abbreviated
d: day in month, not zero padded
dd: day in month, zero padded
EEE: day name in week, abbreviated to three letters
EEEE: day name in week, not abbreviated

The format string may also contain whitespaces and fragments of arbitrary text surrounded by single quotes.

Default Value: MMMM d',' yyyy

`fileTypes.email.timeFormat`

Specifies the format for the rendering of time in email headers.

NOTE: This parameter will be ignored if the __experimental.fileTypes.email.renderMeetingInfo parameter is set to true.

The Sent header value will be composed by concatenating the message's sent date, time and time zone, separated by whitespaces. If fileTypes.email.timeFormat is an empty string, the time will not be displayed as part of the Sent header value.

See Configure Date and Time Headers in Email Documents for additional details.

Supported Values: Must be a string containing zero or more of the following substitution patterns:

H: hour in day (0-23), not zero-padded

The format string may also contain whitespaces and fragments of arbitrary text surrounded by single quotes.

Default Value: h':'mm a

`fileTypes.email.timeZone`

Specifies the time zone for the rendering of date and time in email headers.

NOTE: By default PrizmDoc displays time zone offsets (such as UTC-05:00) rather than time zone names (such as US/Eastern) in email headers. Calculation of time zone offsets takes into account whether the date being displayed falls on the daylight savings time. For example, if fileTypes.email.timeZone is set to US/Eastern, the Sent header of an email sent at 15:00 January 1, 2023 US/Eastern time will display as January 1, 2023 3:00 PM (UTC-05:00), while the Sent header of an email sent at 15:00 July 1, 2023 US/Eastern time will display as July 1, 2023 3:00 PM (UTC-04:00).

NOTE: If PrizmDoc cannot recognize the time zone identifier, it will refuse to start up.

NOTE: This parameter will be ignored if the __experimental.fileTypes.email.renderMeetingInfo parameter is set to true.

See Configure Date and Time Headers in Email Documents for additional details.

Supported Values: See Supported Time Zones. If set to serverTimeZone, PrizmDoc will use the time zone of the server where it runs.

Default Value: serverTimeZone

`fileTypes.email.timeZoneFormat`

Specifies the format for the rendering of time zones in email headers.

NOTE: This parameter will be ignored if the __experimental.fileTypes.email.renderMeetingInfo parameter is set to true.

The Sent header value will be composed by concatenating the message's sent date, time and time zone, separated by whitespaces. If fileTypes.email.timeZoneFormat is an empty string, the time zone will not be displayed as part of the Sent header value.

See Configure Date and Time Headers in Email Documents for additional details.

Supported Values: Must be a string containing zero or more of the following substitution patterns:

z: short time zone name, e.g. "PST"
zzzz: full time zone name, e.g. "Pacific Standard Time"
xxx: time zone offset with hour and minute separated by a colon, e.g. "+03:00".

The format string may also contain whitespaces and fragments of arbitrary text surrounded by single quotes.

Default Value: '(UTC'xxx')'

`fileTypes.email.dateTimeLocale`

Specifies a locale for displaying the date and time in email headers.

NOTE: This parameter only affects the locale of date values, and does not affect email header names, such as “To” and “From”.

NOTE: PrizmDoc will use a supported locale that best matches the specified tag. Exact match is not guaranteed. When setting a specific locale, make sure PrizmDoc displays email headers according to your expectation.

NOTE: Setting an incorrect language tag will cause the locale to default to English (en-US) and abbreviate the names of the months and days of the week.

NOTE: This parameter will be ignored if the __experimental.fileTypes.email.renderMeetingInfo parameter is set to true.

The Sent header value will be composed by concatenating the message's sent date, time and time zone, separated by whitespaces.

`network.clustering.enabled`

Set to true to enable cluster mode.

Supported Values: true, false

Default Value: false

`network.clustering.servers`

The server list can be set once via config, or repeatedly at runtime via a REST API call. Setting the list of servers here is useful if you have a static set of machines that will not change.

When the network.clustering.scheme is set to https, or network.publicScheme is set to https and network.clustering.scheme is set to the default auto value, server addresses specified here must match the Common Name or a Subject Alternative Name specified in the corresponding server's certificate. On production servers, this usually means using fully qualified domain names of your servers.

For example:

network.clustering.servers: ["192.168.0.1","192.168.0.2"]
network.clustering.servers: ["server1.mycompany.net","server2.mycompany.net"]

NOTE: When using PrizmDoc Docker containers in Kubernetes, we recommend that you use the PrizmDoc Cluster Manager to take care of the server list at runtime.

Supported Values: Array containing hostnames or IP addresses of other servers within the cluster

Default Value: -

`network.clustering.scheme`

The scheme used to route requests to other servers in the cluster. Must be one of the following values:

NOTE: this mode is only supported when network.publicScheme central configuration parameter is set to "http".
https - PrizmDoc will use the https scheme for connecting to other servers in the cluster.

NOTE: This parameter only affects the way that the server routes requests to other servers in the cluster, but does not make the server support HTTPS protocol for incoming requests. On Windows, set network.publicScheme central configuration parameter to https to make the server accept incoming HTTPS requests. When using Docker, you will need to set up a reverse proxy on each PrizmDoc instance, and use it as an HTTPS terminator for that instance. See Security Guidance for more details.

`network.publicScheme`

The scheme used to serve public API requests as well as requests from other servers in the cluster. When set to https, network.certificateFile and network.certificateKeyFile must also be defined.

http - Default value. PrizmDoc will use the http scheme to serve public API requests and requests from other servers in the cluster.
https - PrizmDoc will use the https scheme to serve public API requests and requests from other servers in the cluster.

Supported Values: One of the following strings: http, https

Default Value: http

NOTE: This parameter is currently only supported on Windows. When using Docker, you will need to set up a reverse proxy on each PrizmDoc instance instead, and use it as an HTTPS terminator for that instance.

`network.certificateFile`

Path to the TLS certificate file. Required if network.publicScheme is https, and ignored otherwise.

Supported Values: A valid file path

Default Value: ""

For example:

Windows: C:\Config\MyCertificate.cer

Paths that contain environment variables must be quoted. When using double quotes, escape the backslashes:

'%ALLUSERSPROFILE%\Accusoft\Prizm\MyCertificate.cer'
"%ALLUSERSPROFILE%\\Accusoft\\Prizm\\MyCertificate.cer"

`network.certificateKeyFile`

Path to the private key which matches the certificate specified by network.certificateFile. Ignored if network.publicScheme is not https.

If the private key is encrypted, use network.certificatePassphraseFile to specify the path to the file that contains passphrases for the private key.

Supported Values: A valid file path

Default Value: ""

For example:

Windows: C:\Config\MyCertPrivate.key

Paths that contain environment variables must be quoted. When using double quotes, escape the backslashes:

'%ALLUSERSPROFILE%\Accusoft\Prizm\MyCertPrivate.key'
"%ALLUSERSPROFILE%\\Accusoft\\Prizm\\MyCertPrivate.key"

`network.certificatePassphraseFile`

Path to the file that contains passphrases for the private key specified in the network.certificateKeyFile. Passphrases should be listed one per line and will be tried in the order they appear in the file. Mapped network drives and UNC paths are not supported. If you need to use a file which is located on a network drive, consider creating a local symbolic link to the remote file. Please make sure that the PrizmDoc Windows Service account has "Read" permission on the network shared folder.

Supported Values: A valid file path

Default Value: ""

For example:

Windows: C:\Config\MyCertPassphrases.txt

Paths that contain environment variables must be quoted. When using double quotes, escape the backslashes:

'%ALLUSERSPROFILE%\Accusoft\Prizm\MyCertPassphrases.txt'
"%ALLUSERSPROFILE%\\Accusoft\\Prizm\\MyCertPassphrases.txt"

`network.internalStartingPort`

The product requires a range of 200 ports which are reserved for its own internal use. This setting defines the starting port of that range (e.g., a value of 19000 means that ports 19000 through 19199 would be reserved for use by the product). These ports must not be accessible from outside of the server, for security reasons.

Supported Values: Any open HTTP port on the server

Default Value: None (Required)

`network.publicPort`

The public port the REST API will be available on. The chosen port must be accessible by all servers that need to call the PrizmDoc Viewer APIs.

Supported Values: Any open HTTP port on the server.

NOTE: When using PrizmDoc Docker containers, make sure this port is exposed by the container.

Default Value: None (Required)

Process Ids

`processIds.lifetime`

The length of time that a redaction creator, markup burner, content converter, form extractor, search context, search task, or plain text redactor process remains usable. Please see the topic Implement Caching Strategies for more details.

Supported Values: Formatted Value. This must be an integer, followed by s, m, h, or d. The suffixes stand for second, minute, hour, or day, respectively. There should not be any space characters between the number and suffix. For example, 20m indicates viewing sessions will timeout after 20 minutes.

Default Value: 20m

NOTE: For PrizmDoc Cloud, the default value for processIds.lifetime is 5h.

Resource Usage

`resourceUsage.ocs.numInstances`

The number of LibreOffice conversion service instances to run concurrently, or auto to let the product choose an appropriate value.

We recommend using the default value of auto. If you do provide a specific value, it should not be set higher than the number of physical cores available on your server.

Supported Values: Any integer greater than 0, or the string auto

Default Value: auto

`resourceUsage.ocs.numPorts`

The number of ports which can be used internally for communication with the LibreOffice conversion instances, or auto to let the product choose an appropriate value. We recommend using the default value of auto. If you do provide a specific value, it should be no higher than 4 x ocs.instances.

Supported Values: Any integer greater than 0, or the string auto

Default Value: auto

`resourceUsage.ocs.numThreads`

The number of threads each instance should create to handle document processing requests, or auto to let the product choose an appropriate value.

We recommend using the default value of auto. If you do provide a specific value, it should not be higher than 2 x ocs.instances.

Supported Values: Any integer greater than 0, or the string auto

Default Value: auto

`resourceUsage.pccis.instances`

The number of PCCIS ASP.NET application instances to run concurrently.

Supported Values: Any integer greater than 0

Default Value: 3

Security

`security.aesEncryption.iv`

The AES encryption initialization vector (iv) used to create external viewing session IDs.

Supported Values: Base64 encoded value of a byte array representing an AES initialization vector with a size of 128 bits.

Default Value: jTN2XBjybtfA2fpsv6mylQ==

`security.aesEncryption.key`

The AES encryption key used to create external viewing session IDs. The external viewing session ID is an AES encrypted, Base64 encoded value of a string in the format of:

<internal ID>;/<server’s host name>/<Auth-Token header value>

Internal ID - This value is a unique GUID that is internally created by PCCIS for each new viewing session.
Server’s Host Name - Aptly named, this value is the hostname of the server on which PCCIS is running.
Auth-Token Header Value - If the Auth-Token HTTP header exists in the initial POST request to create a viewing session, its value will be used here. Otherwise, accusoft is used. This value is useful if you need to store an authorization token for each viewing session a proxy might need.

See PrizmDoc Cluster Management for more details.

Supported Values: Base64 encoded value of a byte array representing an AES key with a size of 128, 192 or 256 bits.

Default Value: E9rU73lZ2vd0he8Ls/hD8A==

`security.externalContent.requireHttps`

Specifies whether to require the use of the HTTPS protocol for the external content, such as external images in HTML or email documents, external watermarks, or URLs provided for the creation of viewing sessions.

NOTE: The layout of documents (where external content uses HTTP URLs and is not available via HTTPS) may change when you set this parameter to true.

NOTE: Setting this option to true is only allowed when using the LibreOffice rendering engine. If you are using the MSO rendering engine and need all external requests to use the HTTPS protocol, you will need to block non-HTTPS requests outside of PrizmDoc. See Security Guidance for details.

If a URL uses the HTTP scheme, an attempt would be made to access it via HTTPS, except for the case mentioned below:

NOTE: When using the LibreOffice rendering engine, PrizmDoc blocks requests for external content in Office documents and email documents that use RTF bodies, for both HTTP and HTTPS protocols.

Supported Values: true, false

Default Value: false

NOTE: In a future release the default value for security.externalContent.requireHttps will be changed to the more secure setting of true. Setting this option to true will be allowed when using the MSO rendering engine, but in that case you will still need to handle blocking non-HTTPS requests outside of PrizmDoc.

`security.htmlRendering.blockExternalContent`

When rendering any source document which uses HTML content, controls whether or not externally-referenced content, such as images and iframes, will be blocked. This option affects any source document file type which uses HTML, including HTML, EML, and MSG.

NOTE: Changing this setting can affect rendered layout and page count.

NOTE: If you change the security.htmlRendering.blockExternalContent setting, you must clear your cache in order for the new settings to take effect on files previously converted with the old rendering mode.

false - When rendering HTML, issue network requests for externally-referenced content in images, iframes, etc., and include that content in the final output. Any URL accessible from this machine may be loaded and included in the final output. See the Security Guidance page for more details.
true - When rendering HTML, block externally-referenced content in images, iframes, etc. No network requests will be issued when rendering HTML, and the final output will only include the content that is directly present in the source HTML.

Supported Values: true, false

Default Value: false

NOTE: In a future release the default value for security.htmlRendering.blockExternalContent will be changed to the more secure setting of true.

User Documents

`userDocuments.directory`

Supported Values: Any valid path to a directory with read permissions.

Default Value: Windows: <install_dir>/cache/UserDocuments; Docker: /data/cache/userDocuments

For example:

Windows: C:\Prizm\cache\UserDocuments
Docker: /data/cache/UserDocuments

Paths that contain environment variables must be quoted. When using double quotes, escape the backslashes:

'%ALLUSERSPROFILE%\Accusoft\Prizm\cache\UserDocuments'
"%ALLUSERSPROFILE%\\Accusoft\\Prizm\\cache\\UserDocuments"

NOTE: When using PrizmDoc Docker containers, we recommend that you keep this property unchanged.

Viewing

`viewing.allowDocumentDownload`

Controls whether or not the REST API will accept requests to download the source document for a given viewing session.

Supported Values: true, false

Default Value: false

`viewing.cacheLifetime`

The length of time that a document is cached and can be potentially reused by other new viewing sessions.

Supported Values: Formatted Value. This must be an integer, followed by s, m, h, or d. Those suffixes stand for second, minute, hour, or day, respectively. There should not be any space characters between the number and suffix. For example, 1d indicates that data will be cached for up to one day. Please see the topic Implement Caching Strategies for more details.

NOTE: If the amount of time specified by viewing.cacheLifetime is shorter than the amount of time specified by viewing.sessionConstraints.minSecondsAvailable.max, the viewing.cacheLifetime will be changed at runtime to match the amount of time specified by viewing.sessionConstraints.minSecondsAvailable.max. If you change this value to decrease the cache lifetime, make sure that you also adjust the viewing.sessionConstraints.minSecondsAvailable.max value to represent the same or shorter amount of time.

NOTE: For PrizmDoc Cloud, the default value for viewing.cacheLifetime is 43h.

Default Value: 1d

`viewing.contentEncryption.enabled`

Controls whether or not content is encrypted by the back end before being transmitted to a Viewer. The Viewer will decrypt the content in the browser. This is useful for DRM (Digital Rights Management), making it more difficult to copy protected content that has been delivered to the browser.

Supported Values: true, false

Default Value: false

`viewing.sessionConstraints.countOfInitialPages.max`

Maximum allowed value for the countOfInitialPages JSON property when creating a new viewing session. Together with viewing.sessionConstraints.countOfInitialPages.min creates a range filter that will be applied to ensure appropriate values are being set. If the actual property value fails to match the filter, an error will be returned and the viewing session will not be created.

This property is one of several that can be used to limit unwanted values from being used within the JSON properties of the initial POST request to create a viewing session. These filter values are useful for preventing mistaken or malicious values from being sent that could affect server behavior.

Supported Values: Any natural number not less than viewing.sessionConstraints.countOfInitialPages.min

Default Value: 10

`viewing.sessionConstraints.countOfInitialPages.min`

Minimum allowed value for the countOfInitialPages JSON property when creating a new viewing session. Together with viewing.sessionConstraints.countOfInitialPages.max creates a range filter that will be applied to ensure appropriate values are being set. If the actual property value fails to match the filter, an error will be returned and the viewing session will not be created.

Supported Values: Any natural number

Default Value: 0

`viewing.sessionConstraints.documentExtension.regex`

Creates a regex filter that will be applied to the documentExtension JSON property when creating a new viewing session to ensure appropriate values are being set. If the actual property value fails to match the filter, an error will be returned and the viewing session will not be created.

Supported Values: Valid regular expression using the .NET Regular Expression Language

Default Value: .*

`viewing.sessionConstraints.documentSource.allowedValues`

Creates a value filter that will be applied to the documentSource JSON property when creating a new viewing session to ensure appropriate values are being set. If the actual property value fails to match the filter, an error will be returned and the viewing session will not be created.

Allowing a combination of document sources here enables you to create viewing sessions with different sources on the fly without needing to modify this config file. This property is one of several that can be used to limit unwanted values from being used within the JSON properties of the initial POST request to create a viewing session. These filter values are useful for preventing mistaken or malicious values from being sent that could affect server behavior.

NOTE: For PrizmDoc Cloud, the default value for viewing.sessionConstraints.documentSource.allowedValues is api.

Supported Values: Array which contains one or more of the following strings: api, http, file

Default Value: [api,http]

NOTE: In a future release the default value for viewing.sessionConstraints.documentSource.allowedValues will be changed to the more secure setting of [api].

`viewing.sessionConstraints.externalId.regex`

Creates a regex filter that will be applied to the externalId JSON property when creating a new viewing session to ensure appropriate values are being set. If the actual property value fails to match the filter, an error will be returned and the viewing session will not be created.

Supported Values: Valid regular expression using the .NET Regular Expression Language

Default Value: .*

`viewing.sessionConstraints.minSecondsAvailable.max`

This configuration property provides a maximum value that can be used for the option minSecondsAvailable. The value is a positive number and represents seconds. When this value is set to 0, the ViewingSession timeout will be used for validation of the minSecondsAvailable option in the POST /ViewingSession. The default will be 86400 seconds (1 day).

Supported Values: Any integer greater than 0

Default Value: 86400

`viewing.sessionConstraints.pageContentEncryption.allowedValues`

Creates a value filter that will be applied to the pageContentEncryption JSON property when creating a new viewing session to ensure appropriate values are being set. If the actual property value fails to match the filter, an error will be returned and the viewing session will not be created.

Supported Values: An array with either one or all of the following strings: default, enabled, disabled

Default Value: [default]

`viewing.sessionConstraints.render.alwaysUseRaster.allowedValues`

Creates a value filter that will be applied to the render.html5.alwaysUseRaster JSON property when creating a new viewing session to ensure appropriate values are being set. If the actual property value fails to match the filter, an error will be returned and the viewing session will not be created. See the Viewing Sessions and PAS Viewing Sessions topics for more information.

Supported Values: An array with one or more of the following values: true, false

Default Value: [false]

`viewing.sessionConstraints.serverCaching.allowedValues`

Creates a value filter that will be applied to the serverCaching JSON property when creating a new viewing session to ensure appropriate values are being set. If the actual property value fails to match the filter, an error will be returned and the viewing session will not be created.

`workFiles.sharedStorage.type`

Shared storage type for work files. When enabled, the WorkFile Service will store the workfile's metadata in the MySQL database, and the workfile in the AWS S3 bucket.

Supported Values: none, s3. The s3 value means store a copy of each work file in the specified AWS S3 bucket which makes it available to other servers in the PrizmDoc Server Cluster. When used, workFiles.sharedStorage.s3BucketName, workFiles.sharedStorage.path and database.connectionString parameters must be defined, otherwise the PrizmDoc Server will go into an unhealthy state.

Default Value: none

`workFiles.sharedStorage.s3BucketName`

Name of the S3 bucket where work files should be stored, if the workFiles.sharedStorage.type parameter is set to "s3".

Supported Values: Any non-empty string.

Default Value: ""

`workFiles.sharedStorage.path`

Prefix to append to the name of all S3 objects created for uploaded work files, if the workFiles.sharedStorage.type parameter is set to s3. You can think of this as a directory in which all work files should be stored in your S3 bucket.
