Subject: Use copy.deepcopy to clone HTTPRequest when following redirects.
X-Git-Tag: v2.3.0~84
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b7e604646537984e967dd25447a8df3e221bf9ed;p=thirdparty%2Ftornado.git

Use copy.deepcopy to clone HTTPRequest when following redirects.

This gives each request in a redirect chain its own copy of the
headers dictionary.

Closes #459.
