Wow, Mark, thanks. I was doing some testing earlier tonight and a few of 
my pages were fast loading on their own but under load they just ground 
the system to a halt. So this should help.

How do I turn off the caching for a specific directory? I'll need to do 
that on my phpmyadmin and data entry/update dirs.

Thanks again.
