# File: README
"""
 A simple middleware component that lets you use a single Django
 instance to server multiple distinct hosts.
 IMPORTANT!! Make sure this is the FIRST entry in your MIDDLEWARE_CLASSES
 Revision log:
 v1.2 - 10th January 2012 (Cal Leeming - cal.leeming@simplicitymedialtd.co.uk)
  * Added 'LoadingTime' response header (tells us how long the request took to process)
  * Added 'MultiHost' response header (tells us if multihost was used or not)
  * Added 'HOST_MIDDLEWARE_URLCONF_MAP' example
  * Cleaned up code slightly
