What is the correct way to configure .htaccess to send all requests to a unix domain socket?

Ivtried variour enchantement with mod_proxy and mod_rewrite without success.

.htaccess only because I want it to work on shared hostings.

Also, what about NON php fcgi?
I couldn't even get it working with mod_proxy_cgi (again, .htaccess only). The receiving server is up and running, listening at the destination UDS.

Am I missing something obvious?
