iRule to cache extentions in uri after cahce::age > 60

This will definitely break everything unless you have RAM cache enabled for the HTTP profile you are using. Careful enabling this though as it will default to cache everything (bad if you have a dynamic site) unless you specify the proper cache exclusions in the HTTP profile.

 

 

I'm not sure "CACHE::age" is doing what you think it is doing. CACHE::age (http://devcentral.f5.com/wiki/default.aspx/iRules/CACHE__age.html) returns the current age of the cache (on the F5) not the browser.
