If your configuration is broken, migrating to Apache 2.2 and use mod_proxy_balancer will make absolutely no difference since AFAIK ProxyPassReverse works exactly the same way in 2.2 as it does in 2.0. What you could do though is use AJP instead of HTTP for communication with your application server. ProxyPassReverse rewrites the Location header of a HTTP redirect. In order for this rewriting to kick in, the URL prefix must match the argument to ProxyPassReverse. What happens if you remove the ProxyPassReverse directives altogether ? If that changes nothing, your problem is definitly due to the fact that your argument to ProxyPassReverse does not match the redirect URLs issued by Tomcat. If, as you stated in a previous post, whenever you set "ProxyPreserveHost off" you end up being redirected to http://andy/webapp, you need to add ProxyPassReverse http://andy/ (or maybe even http://andy/webapp) to your configuration. -ascs -----Original Message----- From: Bo Najdrovsky [mailto:httpd@xxxxxxxxxxxxxx] Sent: Monday, May 15, 2006 5:26 PM To: users@xxxxxxxxxxxxxxxx Subject: Re: [users@httpd] https to http proxy with Apache Axel-Stéphane SMORGRAV wrote: > In that case my guess is that it is the application that generates > erroneous redirect URLs.

My problem isn't with the whole URL being rewritten correctly, it's only with the fact that it's switching protocol from https to http. However, if I set the ProxyPreserveHost to 'off', then the URL is incorrect as well. I'm thinking that I may try to upgrade the apache to 2.2.2 and attempt to use mod_proxy_balancer. That one looks like it is more suited for what I'm trying to accomplish. --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
