Problem Publishing WCF Ria Application Over Citrix Access Gateway

We currently have a silverlight app, one that uses "vanilla" wcf services and one that uses WCF Ria Services.

We publish the application via a citrix access gateway (secure web proxy).

The SL app that accesses the WCF Service works fine, but the RIA one fails with a ton of "res开发者_运维问答ponse invalid" errors.

If you browse to the service url of either service (using the citrix url), then you see the WCF Service description fine.

Does anyone have any idea of any special config needed to enable WCF RIA Service apps to work over a Citrix Access Gateway?

Can you change the endpoint of the WCF RIA client proxy? Because I suspect it is trying to go to http://your.website.com/yourApp/yourService.svc when it really needs to go to http://your.website.com/cvpn/BIG_HASH_HERE/yourApp/yourService.svc. I have had to jump through some hoops to explicitly support the Citrix Access Gateway in a Silverlight app that I am working on at the moment (will come back later and possibly elucidate further when I have reviewed the code).
