Hi,
I'm having difficulties trying to get PHP caching using header with apache2's mod_cache.
From my understanding, PHP header caching using cache-control and expire needs mod_cache running.
I have set a default timeout in mod_cache but it only caches some contents. Using the PHP header should enable us to cache more stuff and overwrite the expire time set in cache_control.
I've done a few tests where header cache expires after 30 secs which works but afterwards it always refreshes the contents from the server.
Have I missed out something on my view of caching using header and mod_cache? Any help appreciated
