I tried the UDS patch in httpd trunk with mod_proxy_fcgi and PHP-FPM,
and ProxyPass is working nicely now. I used the following config:
<LocationMatch ^(.*\.php)$>
ProxyPass unix:/tmp/php-fpm.sock|fcgi://PHP1${DOCROOT}
</LocationMatch>
One thing worth pointing out is that some unique dummy hostname, such
as that "PHP1" in the above example, is required after the real
scheme. It might be tempting to pick "localhost", but that would
result in problems when using multiple sockets.
Next I tried using UDS with mod_rewrite, but I couldn't get that to
work. Using this config:
RewriteRule /php-info
unix:/tmp/php-fpm.sock|fcgi://${DOCROOT}/ppp/info.php [P,L]
with this URL:
http://localhost:8000/php-info
I got a 404. Turning on tracing for mod_rewrite:

So mod_rewrite is not recognizing the "unix:" prefix as being valid. I
temporarily commented out the call of fully_qualify_uri(r) at
mod_rewrite.c:4130, and now r->filename is set correctly:

but this results in a 500. It looks like mod_proxy is not ready for a
UDS URI in r->filename when it was set by some other module earlier in
the request.
