Subject Re: [users@httpd] ProxyPassReverse problem inside <Location> -- is there a fix?
Date Tue, 17 Jun 2008 23:58:01 GMT
Resending.  The gdccideas URL was meant to be the same as the <target-hostname> URL in
my configuration given in my previous email.  Now I've normalized that to <target-hostname>
below.  Sorry for the poor editing skills :-)
