Could you please help me to better understand how the web server caching mechanism works. I have a Wordpress website with opcode caching (APC). Pages are cached in memory via W3 total cache plugin.

  • Is this plugin take care of the user session management?
  • Is it possible to configure the web server that it will cache the content to APC directly, without this plugin.
  • What's the recommended solution in this case?

I've tried with nginx and FastCGI cache but apparently this it's not generally safe as it may cause private pages (and/or cookies) to be cached and returned to other clients.

if you are able to, i would recommend to go with Memcached. It's the standard way to do it and there are many plugins for Wordpress. It worth a try!
