Subject svn commit: r349723 - /httpd/httpd/trunk/modules/proxy/proxy_util.c
Date Tue, 29 Nov 2005 15:05:19 GMT
Author: jim

New Revision: 349723

URL: http://svn.apache.org/viewcvs?rev=349723&view=rev
Log:
Fix case where a shared keepalive connection results in
different workers from being accessed. Try to be wise and
fast about the tests before we do the expensive string
comparison.
