I'm trying to run a Silverlight-application, which makes calls to a nested webapplication in which I have implemented Microsoft's SignalR Hub. The Silverlight-application has a SignalR Client, which tries to connect with the Hub over https at startup.
In the webapplication that hosts the Silerlight-XAP-file, a request is made to the SignalR hub to negotiate the transport protocol. This request fails, a 302 status code is the response and ForeFront Manager shows that FBA-Cookie exists="no"
The request being made is to the route URL .../HubWeb/signalr/negotiate?.....
A request to any other file in this same "HubWeb" webapplication responds with 200 and the FBA-Cookie does exist.
Also the call to /Hub/signalr/hubs shows the Javascript-file the SignalR-hub renders, as expected.
What could the reason for this particular request to fail and lose it's FBA-Cookie?
If any more info could help, I'd be glad to supply it.
Thanks in advance for your advice
