Help Setting up GeoServer Proxy with OpenLayers

I have a GeoServer WMS in Apache-Tomcat at http://localhost:8080 and a mod_wsgi app in standard Apache at http://localhost:80/myapp.

My OpenLayers map is being hosted statically by the Apache-Tomcat Geoserver app at http://localhost:8080/geoserver/www/OL.html. The JavaScript in this map has to call the mod_wsgi app for non geographic data.

I've tried setting up a proxy in GeoServer the following ways

http://localhost:80/mypp

http://localhost


localhost

None of these work. After making a request some of my response object attributes look like this which means it's not really working. GeoServer logs show no errors

priority "NORMAL"
readyState 4
responseText ""
responseXM Lnull
status 0
statusText ""

Can't say I'm too much of an expert at Proxies. But it seems to me that I wouldn't need to set up a OpenLayers proxy (as mentioned here) if GeoServer can proxy for me.

Ideas, hints, advice?
