Applies to: SharePoint Server 2010

Event ID:   5787

Summary:   To save time accessing frequently used static files, Microsoft SharePoint Server 2010 uses the disk-based cache to store these files on the disk of the front-end Web server instead of accessing these files directly from the database server. Farm administrators can configure settings for the cache by modifying the Web.config file on each front-end Web server.

This alert indicates that the configuration settings of the disk-based cache are not valid.

Symptoms:   The following event appears in the event log: Event ID: 5787 Description: Unable to connect publishing blob caching. Web.Config is not set up correctly. Cache is not valid. WebId is '<webid>', Url is '<url>'.

Cause:   The configuration settings of the disk-based cache are not valid.

Resolution:   Correct the configuration settings in the Web.config file
