`Expect-Continue`
^^^^^^^^^^^^^^^^^

Since `httplib <https://bugs.python.org/issue1346874>`_ does not support the
`Expect-Continue` header, a request with a body will fail with
``401 Unauthorized`` and must be repeated with a GSSAPI exchange. This causes
several issues:

* Additional overhead for request retransmission
* Requests with non-repeatable bodies will fail
* Some servers will already send the approriate error response while your
client is still streaming the request. Not all reverse proxies can handle that
properly and will rather fail.

Therefore, in such cases you must enable opportunistic authentication.
