proxy_cache seems not working with X-Accel-Redirect

[bdesemb]

I want to add some clarification. My client calls is like "/app" and the
server respond with a name. My file is stored at /var/local/data/<name>. I
want to cache the response. So if I have another request on /app, Nginx
should respond with the cached version of the file.
