I've noticed that urllib2's HTTPRedirectHandler does not redirect a POST request with the POST data.  

If you send a POST request to a server with data, the data is dropped when the new Request is made to the new url.  As stated in a comment in the library itself, redirecting a POST request is not strictly RFC compliant, but it's generally supported anyway.  The problem here being that our POST data is not also being redirected.  I ran into this issue when writing a web api wrapper in Python.

I'm submitting a small patch that fixes this issue:
