    ARR v2 Caching and ASP.Net Works Great, Why?

    Reply Contact

    I would like to understand how ARR disk caching works with ASP.Net applications and have not been able to find a good reference.

    I have a simple testing server farm configuration with a single ARR server and a few content servers.  Everything with my ASP.Net application is caching appropriately, static images and CSS sheets are cached and dynamic data is excluded.   I do not understand how this is working.

    I have browsed through the web.config file for the application, but I am just not seeing it.  Can you give me a gentle nudge in the right direction.

    Thanks in advance.

    ARR caches based on response headers - specifically Cache-Control, Pragma, Expires, Last-Modified, Etag - you can read the caching section in rfc2616.

    As Anil has pointed out, there is nothing "special" that ARR does for ASP.Net.   ARR caches contents based on "cache-ability" of the content, as defined by RFC.
