The library version being used is 7.11.0-20031217. Compiled under OS X
10.2.8 with --disable-ipv6.

When curl issues a PUT (or other custom header the pushes data) is not
including the "Content-Length" header initially. This causes a HTTP 411
Length Required error to be returned by the server. With our users it
seems to be a problem with IIS 6.0 on Windows 2003. On Windows 2000,
IIS 5.0 responds with a challenge request and when the properly
authenticated request (e.g. PUT) is reissued it does contain the
"Content-Length" header and succeeds as expected.

We do not have enough knowledge of curl to propose a fix we are sure
would not break something else. But, we suspect these lines in http.c
introduce the problem:

  if(!authdone)
       /* until the auth is done, pretend we only do GET */
       httpreq = HTTPREQ_GET;
  else
       httpreq = data->set.httpreq;

This will cause the default case to be hit in the switch statement that
follows and since that case treats the request like a GET the header is
obviously not set.

Here is the curl log illustrating the error as reported by a user
(slightly censored):

* About to connect() to xxx.xxx.xxx port 443
* Connected to xxx.xxx.xxx (xxx.xxx.xxx.xxx) port 443
* error setting certificate verify locations, continuing anyway:
