Comment:

 The fix is actually a bit more complicated than that, because we cannot
 assume that `host` is of the form `domain:port` (it could be an IPV6
 address or even complete garbage).

 I took a crack at it in my PR: https://github.com/django/django/pull/912

 I also wonder if it'd be a good idea to validate `settings.ALLOWED_HOSTS`
 (we could make sure that's it's a list, and that no entry contains a port
 number).
