New submission from Jonathan Guthrie: This is related to issue 5111.
An IPv6 link-local address must include a scope specifier as part of the address passed to the HTTPConnection or HTTPSConnection constructor, that scope specifier is not being stripped from the address passed in the HTTP 1.1 Host: header line. So, suppose I was attempting to connect to an HTTP server on fe80::8aae:1dff:fea4:29c8. That's a link-local address, so I must give the scope specifier, which is the interface I can use to connect to that address. So, the address I would pass to the HTTPConnection constructor might look like "fe80::8aae:1dff:fea4:29c8%eth0". The appropriate Host line in the HTTP request would be "Host: [fe80::8aae:1dff:fea4:29c8]" but it is actually "Host: [fe80::8aae:1dff:fea4:29c8%eth0]" Compliant HTTP servers reject requests including this line as malformed. ---------- messages: 286276 nosy: JonathanGuthrie priority: normal severity: normal status: open title: httplib: wrong Host header when connecting to IPv6 link-local address type: behavior versions: Python 2.7, Python 3.5 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue29375> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
