Hello, I have a dedicated server with WHM/Cpanel. I have Apache 2.2. and most of the accounts on the server run Drupal sites, a couple of Wordpress blogs, and a couple of OpenX Adserver instances. I'm wondering what the purpose or (or when to use) the Apache modules mod_cache and mod_mem_cache. I searched this forum and didn't find much on the topics. Also, on the Drupal discussion forums, I'm seeing alot about installing memcached and the PECL memcache php extension, and APC. Does anybody have any advice on how to proceed, and is there any conflict with memcached, pecl memcache, and APC with Cpanel?
