I have a mono web application running with this virtual host below. It is running on Apache 2.2.20 / Ubuntu 11.10. I tried to add a reverse proxy inside this virtualhost so I can make asynchronous or AJAX type calls back to this same domain. My asynchronous requests would have problems in many browsers calling services that are on another domain (cross domain requests problem). I am wanting to do reverse proxy calls to this other service using http://www.whatever.com/monkey/. So, I added the directive and top directive to try to make this work. It is weird though...nothing I do seems to have any effect. I can put the exact same markup in my default website virtualhost file and it works great. What is the deal? Are some of these Mono directives causing problems?
