Hi Zafer,
You can check the cache wiki page (Click here) for details on the commands. It looks like you can get the age of the cached object using CACHE::age. You can expire a cached object using CACHE::expire. You can view the cached objects from the command line using 'b profile http HTTP_PROFILE_NAME ramcache entry all show'.
I ran into a bug on 9.4.5HF2 when explicitly enabling caching in the HTTP_REQUEST event of an iRule. If the request doesn't contain a host header and the request matches the test to explicitly force caching with CACHE::enable, TMM will crash. F5 noted this in CR108998. The workaround is to either check for a host header, or more ideally, let the caching be enabled in the HTTP profile and then selectively disable it when your caching criteria isn't met.
