This is a valid configuration snippet (AFAIK) but it won't do what you
probably expect. It defines two upstream servers, one running on a unix
socket and one on TCP. The protocol that Nginx speaks to them depends on
whether you use proxy_pass or fastcgi_pass. AFAIK you cannot balance
between a FastCGI backend and a HTTP backend.

You could also run the remote PHP over FastCGI and just use FastCGI
everywhere. I think that php-fcgi -b 10.0.0.200:8080 or something
similar will do the job (but I'm sure Mike will step in and tell you how
to use php-fpm in such a setup ;))
