The changes in mono are changing threading. This means that the code is getting deadlock in the ReadStreamData. This happens because we were not removing the handlers from the first requests events. Initially, before we had to take care about the auth headers, this was needed to init certain internal state for the HttpContent that was sexposed to the user. With the fix of the CVE, the first request, in case of a redirect, is garbage and is ignored. The second request is the one returned to the user and contains all the required info. Removing the event handlers, ensure that HandleClose is not called and therefore ReadStream is never called.

I ran the monotouch-tests on simulator on two macs, and on my iPad. All passed 👍 |
