urllib2.py version 1.72 uses capitalize() on HTTP header names. This results in headers like "User-agent" instead of "User-Agent". This causes HTTP 400 errors on some servers when the request has a body, because there are two content length headers placed in the request: "Content-Length" (inserted by httplib) "Content-length" (inserted by Request.add_unredirected_header) The capitalization is incorrect, and httplib inserts Content-Length anyway, so I'm not sure why urllib2 is bothering.

Logged In: YES user_id=849994 It is. This bug report was about duplicate headers in the request, while the one you mention is about the capitalization per se.
