Comment 1 for bug 612096

Python 2.7 changed some of the expectations about what xmlrpclib needs from a custom transport implementation. We wrote a custom one because the built-in one doesn't support http proxies. However, we need to update it to now provide the extra facilities. (xmlrpclib now tries to support both Keep-Alive and Content-Encoding: gzip, though should that actually be Transfer-Encoding?)
