Proxy Problem

I put this in my httpd.conf to route a domain directly to one weblog. This works fine but the weblog has wrong links. Images, stylesheet and all links don't work. It puts the directory weblog23 on top on the existing one in the proxy. Any suggestion how to solve this problem.

Thanks
