Hello -
I've implemented 2 different custom TiledMapServiceLayer layers. Everything is working well, but I'm seeing something unexpected. I never see requests for clientaccesspolicy.xml or crossdomain.xml when Silverlight requests tiles via these custom TiledMapServiceLayer layers. I've verified that I don't have anything cached, and that Fiddler is picking up traffic from the servers in question. The tile servers are different than the server Silverlight is hosted on, which is why I was expecting these files to be requested.
Does Esri's base class implementation somehow get around the typical Silverlight security mechanisms for these outbound cross domain requests? Any ideas?
