> You could certainly do a reverse proxy and use HTTP instead of FastCGI as the protocol between the client facing httpd and the application server

That's what I meant. Things like X-Sendfile (or X-Accel-Redirect in nginx) works with http backends. Why involve a different protocol to transfer a HTTP request to a backend instead of... HTTP? I really don't get the point of FastCGI over plain HTTP when a reverse proxy is talking to a upstream backend server.

I mean, that protocol doesn't really matter to me, that's why I said "FastCGI or some other method" The important bit is avoiding fork+exec on every request.

FastCGI is binary based, which has benefits, but hopefully a reverse proxy sends well-formed HTTP requests ... but maybe having the application runtime provide an http frontend encourages running the application software directly accessible, which isn't always wise... some of them are really bad at HTTP.
