Hi igor,

I made a patch which add two new directives:
proxy_cache_ignore_headers and fastcgi_cache_ignore_headers. By
default, they are set to off and everything works as before. When set
to on, pages are cached even if Expires or Cache-Control said not to.

I need to cache pages even if the backend said not to because I don't
have access to the backend code and no one can :(

The patch is attached. I've tested it with proxy but not with fastcgi.
As the patch is simple, it should not be a problem.

Hope it would help.
