Enabling Gzip Compression in IIS on Windows

An easy way to improve performance and loading times is to make sure that the page content sent from the PCC server to the browser has been Gzip-compressed. If you have installed PCC on a Linux machine, this happens automatically. If you have installed PCC on Windows, there are some changes you will need to make to your server and to IIS to ensure that document content is Gzip-compressed.

To enable Gzip compression on your Windows PCC server:

Make sure that the Dynamic Content Compression feature has been enabled for IIS in Windows.

See http://www.iis.net/configreference/system.webserver/httpcompression#003

Add a server-level rule to httpCompression.dynamicTypes that enables dynamic compression for image/*.

From the command line:

appcmd.exe set config -section:system.webServer/httpCompression/+"dynamicTypes.[mimeType='image/*',enabled='True']" /commit:apphost

Restart IIS.
