The attached patch enables caching for FastCGI. The directives are the same
as in proxy cache, just change proxy_ prefix to fastcgi_ one. Plus

fastcgi_cache_key  127.0.0.1:9000$request_uri;

to evaluate unique key in cache. In proxy the key is evalueyed intrnally
is something like

$schema$proxy_host:$proxy_port$uri$is_args$args
