WPFC install disable caching for _SERVER variables

I have installed wp with fast cache and it works great but it caches all _SERVER variables and that includes _SERVER[“REMOTE_ADDR”] and _SERVER[“HTTP_USER_AGENT”] and i require these in WP. How can i tell fastcgi to not cache these variables,or to rewrite them once cached version of file is found.

Sorry, buddy, but if you need these variables for your blog to work, it is not eligible for any caching mechanism, IMHO.
