Rewriting Apache response headers during redirect
Posted on 2008-10-23
My client has a setup whereby they have just moved their application server into a DMZ. At the front-end they have an SSL-offloader which accepts SSL requests and converts to HTTP requests which are then forwarded onto the Java application.
This works fine except when the application send a redirect to the browser. The redirect is to an HTTP URL which is ignored by the SLL-offloader.
I'm looking for a solution not involving rewriting any of the application code. The application is hosted on Tomcat with Apache at the front-end. My proposed solution is to use Apache to rewrite the response header so http becomes https. I'm sure this can be done but I'm struggling with the implementation.
The things I know so far
- I want to rewrite the location value
- I can use mod_headers to set the new value in the header
- I could possibly use Perl to do the rewriting but am not familiar with Perl
Any help appreciated.
