I am occasionally seeing a NSURLErrorUnsupportedURL (unsupported URL) error being returned by download tasks on a background NSURLSession, on iOS. Before you ask, the URL (https://…) is properly formed, [NSURL URLWithString:] returns a non-nil URL, and as an extra manual check I did an online validation of the URL on a couple of different websites to see if I missed something.
The time between when the request is made and when it completes with an error might be a minute or so, so the framework is immediately bailing on the request. I'm wondering what part of the process generates the error. Does the server return a non-200 status code or what? Searching for more detail in the docs, etc., hasn't yielded anything except comments from people saying to make sure that the scheme is specified. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
