## nginx
nginx includes an undocumented, internal socket-passing mechanism based on the `NGINX` environmental variable. It uses this to perform reloads without having to close and reopen its sockets, but it's also useful for socket activation.

This configuration is possible with any web server that supports FastCGI (like Apache, Lighttpd, or nginx). The web server does not need to know anything special about the socket; use a normal PHP-FPM configuration.

It's possible to shut down the service and re-activate it using the web browser, too. It's necessary to stop and start the socket to reset some shutdown PHP-FPM does that otherwise breaks reactivation.
