PrizmDoc v13.4 - Updated
Affinity Tokens & Cluster Mode
In cluster mode only, requests for WorkFile, MarkupBurner, RedationCreator, and ContentConverter resources require an additional bit of data, called an affinity token, to ensure they are routed correctly by the Cloud Entry Point (CEP). The affinity token is a Base64 encoded string that contains encrypted information necessary to route related requests to the same PrizmDoc server. Getting related requests to the same server is critical as the necessary data is cached locally.
In cluster mode, the PrizmDoc Back-end RESTful Services will automatically generate an affinity token when it receives a POST request for a new ViewingSession, WorkFile, MarkupBurner, RedactionCreator or ContentConverter resource and return it in the response. Once you have obtained an affinity token, you will need to pass this in with related requests using the "Accusoft-Affinity-Token" HTTP custom header. In the case of a ViewingSession, the affinity token is only required when retrieving or setting the source document WorkFile ID for that session.
The following example request and response sequence demonstrates how an affinity token is used to burn markup into a document. Notice how all requests, (except the first request), use the same affinity token even for subsequent POST requests.

Likewise, the following request and response sequence demonstrates how an affinity token is used in a content conversion workflow:
