reverse and url tag should reverse urls without need of hostname in case of uniqness

[professormahi]

As said in docs we must pass host-name in both reverse function and url template tag.

I think it should be better if we could use something like {% url 'view-name' %} in a case that we don't have same view-names in different hosts. Or something like reverse(view_name) in such cases.

May I add this feature and make a merge request?
