- Test cases 1051, 1052 and 1055 were added by Daniel Fandrich on July 30 and

  proved how PUT and POST with a redirect could lead to a "hang" due to the
  data stream not being rewound properly when it had to in order to get sent
  properly (again) to the subsequent URL. This is now fixed and these test
  cases are no longer disabled.
