Forwarding PHP requests via ProxyPassMatch as a handler, or only when file exists
One option is to install mod_proxy_handler: https://gist.github.com/progandy/6ed4eeea60f6277c3e39
Or you can wait for Apache 2.4.10, which should include the module.
Basically the module lets you do this:
#tcp
<FilesMatch \.php$>
SetHandler proxy:fcgi://localhost:9000
</FilesMatch>
#uds
<FilesMatch \.php$>
SetHandler "proxy:unix:/path/to/socket.sock|fcgi://./"
</FilesMatch>
Just for the record as a one liner:
AddHandler "proxy:unix:/path/to/socket.sock|fcgi://./" .php
You'll need a recent Apache 2.4 (RedHat back ported that to 2.4.6)
