Update in File Caching in EPiServer CMS 5 R2 SP2

Update

The ASP.NET output cache for files is now turned off by default in the EPiServer CMS 5 R2 SP2 release. Please note when upgrading to EPiServer 5 CMS R2 SP2 this update may require consideration.

In the EPiServer 5 R2 SP2 release a new attribute has been added on staticFile this is called enableOutputCache - turning this attribute on enables the output caching of ASP.NET files.

Background

In versions EPiServer CMS 5 R2 and EPiServer CMS 5 R2 SP1 the output cache causes a problem where files were not getting updated until the server cache expires. (This only happened for files where expirationTime in web.config was set to a positive value - a workaround for this was to force cacheControl to “private”, or set expirationTime to a negative value).

For further background information see the post - Files being cached too aggressively in R2.

Improved Web Browser Support

EPiServer CMS 5 R2 SP2 now has full support for Internet Explorer 8 as a browser for editing.
