My site is powered by Joomla! There is a component I would like to add called com_page_cache since my page loads somewhat slowly. One of the criteria for installing the component is that I have access to $_server variables. I've tried my best to figure out if I do, in fact, have access to this with no luck. So my quesiton is, do I?
Sincere thanks in advance for any reply!
FWIW I'm on a shared hosting plan.
