These commits fix a regression and a bug that were preventing POST requests from working when the initial request fails with 401 Unauthorized and a WWW-Authenticate header, and the client retries with a proper Authorization header. Also add tests to catch these problems in the future.

@nylen nylen Fix a regression introduced by cba36ce
Request.prototype.init() should not clear self.method if it is already
set.  This is relevant when retrying requests with proper authentication
(the retries are handled similarly to redirects, but should keep the
same request method).
@nylen nylen Don't delete headers when retrying a request with proper authentication edc2e17
@nylen nylen Refactor and expand basic auth tests
The new tests catch the regression corrected by c40993f and the bug
corrected by edc2e17.

Why isn't this change integrated with request yet? I just wasted 80 minutes of my life because I had to track this problem down...

This still seems to be a potential issue. The following code does not seem to work as expected, though other requests are being correctly retried. Url, callback, and attachments have all been verified (attachment.content is a Buffer).

var form =, callback).form();

options.attachments.forEach(function (attachment) {
  form.append(attachment.generatedFileName, attachment.content);

The POST is never retried after the first response (401) when this request is made, and the callback is never called.

@wprl, can you provide a failing test case?
