Answer 1

The problem appears to be that someone changed the URL without telling us, and they put a redirect in place. HttpClient is responding to the redirect, but ends up actually sending the request to the final destination as a Get.

This seems like a bug in HttpClient to me, that it should either send the ultimate request as a Post, or throw an exception saying it can't do what I asked it to.
