I am using W3TC on a a wordpress 3.0 network that I run on a VPS. I have it working fine with APC for page caching, minify, and database caching.
However I would like to have it use Disk Enhanced for page caching as I hear that it is faster. For some reason I can't get it to work. I don't use .htaccess files on my server and put all the rules in the apache server config (so all my regular wordpress rules are there). I tried putting the rules that W3TC said I should put in the .htaccess files in my server config but it doesn't work.
What I am seeing is that the root site works fine and pages are cached. However any subdomains are not working. I have the plugin network activated.
Anyone have a solution to this problem.
