Subject svn commit: r1227642 - /httpd/httpd/trunk/modules/proxy/proxy_util.c
Date Thu, 05 Jan 2012 15:45:02 GMT
Author: covener
Date: Thu Jan  5 15:45:01 2012
New Revision: 1227642

URL: http://svn.apache.org/viewvc?rev=1227642&view=rev
Log:
Update the comment and checks around address/connection reusability
in mod_proxy.  

The checks and comment are a vestige of 2.0.x
mod_proxy_http where the backend proxy conn was stored in 
the frontend r->conn_config, but ap_proxy_determine_connection()
doesn't associate the frontend and backend conns like this.
