[Users] Still stuck on proxy and WMSCapabilitiesStore

[Jason Woolard]

hi -

I've been working with the wms capabilities store example to try to 
retrieve an external getcapabilities doc using the python proxy.cgi and 
display a grid view. I've added the external wms host to the proxy.cgi 
script and I can test the proxy by typing 
"http://localhost:8080/proxy.cgi" in my browser (running a localhost 
python cgi) and it returns the OpenLayers home page. So, I can assume 
it's working as expected (python is being called, etc.)?  I can also 
type the url of the getcapabilities doc in my browser 
'http://hdds.usgs.gov/ArcGIS/services/201004_OilSpill_GulfOfMexico/MapServer/WMSServer?request=GetCapabilities' 
and it returns an xml doc.

Should I now be able to do something like this or am I completely off track:

Ext.onReady(function() {

     OpenLayers.ProxyHost = "proxy.cgi?url=";

     store = new GeoExt.data.WMSCapabilitiesStore({
         url: 
'http://hdds.usgs.gov/ArcGIS/services/201004_OilSpill_GulfOfMexico/MapServer/WMSServer?request=GetCapabilities',
         autoLoad: true
     });
     store.load();

etc.......

It's not showing errors in the console. The page just isn't loading so 
I'm guessing it's still same origin policy stuff?
Thanks in advance for any tips.
