Comment:

 This has been resolved using the `Use of the 100 (Continue) Status`
 feature of `HTTP 1.1`. Before sending the entity request body, we check if
 the server accepts the authentication credentials and only continue if
 `100 Continue` is returned. It looks like this running against Apache2:
