Sometimes you want to generate a really absolute URL, but the built-in url tag only generates a URL relative to the current domain. This context processor adds the extra information needed to the request context, so you can generate an absolute URL in a template like so:

{{ protocol }}://{{ domain }}{% url someview %}

This is similar to how the password reset email from contrib.auth generates the full URL in the email.

Save this somewhere as context_processors.py (or add to existing file if you have one), and add context_processors.site to your TEMPLATE_CONTEXT_PROCESSORS setting.

from django.contrib.sites.models import Site, RequestSite

def site(request):
    site_info = {'protocol': request.is_secure() and 'https' or 'http'}
    if Site._meta.installed:
        site_info['domain'] = Site.objects.get_current().domain
    else:
        site_info['domain'] = RequestSite(request).domain
    return site_info

The absolute url might also include a specific port. So that should be also included into the snippet.
