Unix sockets for fastcgi_pass

[Chris Savery]

Hello,

I just tested out using unix sockets for fastcgi_pass instead of the 
often seen 127.0.0.1:9000.
It worked fine as far as I could tell.

Is there some reason no one seems to do this? I've read that sockets are 
faster (don't know how much though) and probably more secure since they 
aren't potentially exposed to the net. So that sounds better to me but I 
see everyone seems to configure php using 127.0.0.1:9000.

Unix sockets only work on the same machine, right? So that would knock 
it out for many situations. But for my use right now this would work. Is 
there another reason not to do it?

Chris :)
