Hello, I am talking to a certain REST server (you can sign up for free, so if you care I will gladly tell you), but when I try to provide basic auth credentials using URLSession:didReceiveChallenge: (which is being called), I receive a 401. If I add the Basic Auth to the headers, everything works. Smart people on the list: Am I doing it wrong? Or is the server behaving oddly? Thanks Alex _______________________________________________ Do not post admin requests to the list. They will be ignored.
