Description

I'm using domain name like xxx_yyy.abc.com and I get "Bad Request (400)" when DEBUG = False.

I happened to be so that split_domain_port(host) from django/http/request.py returns a pair of empty strings as host_validation_re doesn't allow underscore.

I agree that according to RFC it's not possible to have underscore in a hostname, but here we are dealing with domain names and it's totally fine to have underscore in a domain name.
