How can the LTM check if cached content has changed on the server

I have configured the LTM to use caching via a http_profile.

 

How can I configure the LTM to check if the static content on the server, which is cached on the LTM, has changed via time-stamp or content size.

 

If it has changed is should get the new content otherwise it can get it from cache.

 

 

currently I am clearing the content manually from the cache with a bp command.

    Hi Richard,

     

     

    RAM cache is a simple memory cache of files. It cannot check if the file attributes have changed. You could test the Aging options on the HTTP profile and see if you can get something working to expire the cache sooner. Else, the Web Accelerator module offers more complete intelligent caching.
