Most likely this is caused by mod_proxy rewriting the URL then. It's common for proxy code to rewrite URL for various purposes. There is usually a way to turn off URL rewriting in proxy, but I'm not familiar with apache enough to tell you exactly what to do. Hope you can find the document on that and turn that off.
There's probably something wrong with UserServlet (part of zimbra code) as well where the code was not written defensively. That's why it doesn't like the rewritten URL. If you figure out what the rewritten URL is, let us know and that will help us see what's wrong with UserServlet. Thanks! |
