http purging multiple accept-encoding entries

[Chris Hecker]

Awesome, this worked great, thanks!

The one caveat that others might run into was that sometimes the backend 
would sent / as the url, and I was using the regexp ~ version from the 
link you sent, so it would clear the whole cache.  I changed it to this:

                 purge("req.url ~ " req.url "$");  # use regexp to 
handle all Accept-Encoding's
                 error 200 "Purged in recv.";

and now it works perfectly.
