In that case my guess is that it is the application that generates erroneous redirect URLs. Had tomcat generated the redirect URLs, theyr would have contained the port number also, e.g. http://andy:8012/ Keep your configuration the way it is (ProxyPreserveHost Off) and add the following to the configuration: ProxyPassReverse /mywebapp/ http://andy/ or ProxyPassReverse http://andy/ (if within a Location) -ascs -----Original Message----- From: Bo Najdrovsky [mailto:httpd@xxxxxxxxxxxxxx] Sent: Friday, May 12, 2006 10:18 PM To: users@xxxxxxxxxxxxxxxx Subject: Re: [users@httpd] https to http proxy with Apache Brian Rectanus wrote: > > It would help to post the tomcat-workers.conf, but I'll take a guess > and assume this is what it looks like: > > LB1 andy:8012 > LB2 andy:8022 > LB3 andy:8032 > LB3 andy:8042 > ALL andy:8012|andy:8022|andy:8032|andy:8042 Yep, that's exactly what it looks like. > > Does it make a difference with ProxyPreserveHost Off?

Well, if set ProxyPreserveHost to Off, then the URL's actually change from the original host to http://andy/webapp (i.e. the back end server) Notice that they still lose the https and change to http. > > Anyhow, just a shot in the dark. > > -B > > --------------------------------------------------------------------- > The official User-To-User support forum of the Apache HTTP Server > Project. > See <URL:http://httpd.apache.org/userslist.html> for more info. > To unsubscribe, e-mail: users-unsubscribe@xxxxxxxxxxxxxxxx > " from the digest: users-digest-unsubscribe@xxxxxxxxxxxxxxxx > For additional commands, e-mail: users-help@xxxxxxxxxxxxxxxx > --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
