The tempcache is a directory that is used for sharing files between the PCC for SharePoint Integration and the Prizm Content Connect Services. Files in the tempcache are written and modified by both the web tier and PCC Services.

A correctly configured tempcache is critical to proper functioning of document viewing and security of the PCC for SharePoint deployment. The integrator should take proper care to ensure that permissions of the tempcache folder are set to permit read and write by the web tier and PCC services, and also to ensure that permissions are set to prevent unauthorized access.
