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.
