This works with Django 1.0.0
and later. It sets the request.urlconf
variable to an alternate urlconf, if there's a match to the hostname in settings.MULTIHOST_URLCONF_MAP

# A simple middleware component that lets you use a single Django
# instance to server multiple distinct hosts.
#
# Example usage (in settings.py):
# MIDDLEWARE_CLASSES = (
# ...,
# 'django_multihost.MultiHostMiddleware',
# )
# MULTIHOST_URLCONF_MAP = {
# 'domain1.com' : 'app1.urls',
# 'domain1.com:8080': 'app1.urls',
# 'domain2.com' : 'app2.urls',
# }
#
# If a host wasn't found, settings.ROOT_URLCONF will be used.
