I have a Silverlight application that uses a WCF duplex service (Service1) using a pollingDuplexHttpBinding binding and a polling window of 15 seconds.
I have another service (Service2) which is a pretty standard basicHttpBinding, hosted on the same domain.
The problem that I am having is that calls to Service2 time out. This only happens when Service1 is active. There is basically a permanent connection to Service1 and it looks like Silverlight, or the hosting browser (Firefox 4, in my tests), can't make a call to Service2 while polling on Service1.
I know that browsers topically limit the number of simultaneous connections to a domain, but 1 seems a bit low?
