Subject: Spacen Jasset reported a problem with doing POST (with data read with
 a callback) over a proxy when NTLM is used as auth with the proxy. The bug
 also concerned Digest and was limited to using callback only. Spacen worked
 with us to provide a useful patch. I added the test case 547 and 548 to
 verify two variations of POST over proxy with NTLM.
