# File: django_multihost.py
#
# 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.
#
