This looks like a bug in MT 4.2 new feature: "iOS Proxy support: we now pick the system proxy settings and use those in .NET APIs. The new CFProxy type can be used to get to all the details." As a workaround, try to set request's Proxy property like this: request.Proxy = GlobalProxySelection.GetEmptyWebProxy(); Robert _______________________________________________ MonoTouch mailing list [email protected] http://lists.ximian.com/mailman/listinfo/monotouch
