Subject Re: UDS support for mod_rewrite
Date Wed, 22 Jan 2014 15:36:22 GMT
Yeppers... The key thing to remember that it was only
pre-existing workers (ie: those defined) that could
be associated with UDS, and so if you could "trick"
mod_rewrite (or anyone else) to use that worker, you
were golden.

The problem was the mod_rewrite, in general, would use
the generic reverse proxy worker, and so I needed to
add code that would see if rewrite had forced a proxy:
and then adjust that generic worker accordingly.

Your "hack" has the additional benefit is being
a pooled connection and not a one-shot, and therefore
will have better performance. But that isn't related
to UDS at all.
