Description

I've got a FastCGI (PHP-FPM) backend-server which will do some preprocessing and return an X-Accel-Redirect header to tell nginx to serve the file. I would like nginx to cache this response; not the actual response to the client but just the mapping from $request_uri to the headers returned by FPM. On subsequent requests nginx could get that reply from the cache without bothering FPM and resolve the X-Accel-Redirect and serve the file.

(In my case I would like to use X-Accel-Expires to tell nginx it can cache the request.)
