A Complete Caching System

I have been using Total Cache for a while and never had any issues with it and I run it on many sites. I use the free version which has all of the features that a small website needs. It is feature complete and no caching setting has been left out. I am am impressed in the amount of thought has gone into this plugin. When you first set it up there is a learning curve, but the documentation really helps with this and when you have the perfect setup you can export your settings and use them on your next site. I have asked on the support forum for a few things and the developers were kind enough to help me. I would not consider using any other caching software so when any of my sites grow enough and require better caching features, I will upgrade to Pro.
