Proxy cache for php site

[Jon Bennett]

Hi Appa,

I've implemented what you suggested, and although got no errors, it
doesn't look like it's caching, no files appearing in the cache dir
(which I've 777 just to be sure!) and not getting a high rps either.

I'm tailing my nginx error log with nginx compiled with debug, and
there's nothing in there about fcgi cache.

Bit of a weird one, will investigate further.

Thanks,

Jon
