My web site is hosted on Windows. I installed WP Super Cache. It works great for reducing first bite time to 0.3 - 0.4 ms (when I used W3 Total cache, the first bite time was several seconds) and using CDN. The problem is that it does not cache at all because of the mod_rewrite issue. I also tried "Use PHP to serve cache files", it doesn't work either. Anyone knows how to set up it?
Thanks a lot.
