   Fixed #15089 -- Allowed contrib.sites to lookup the current site
   based on request.get_host()
   get_current_site() will now lookup the current site based on
   request.get_host() if the SITE_ID setting is not defined.

   threadlocals
   from threading import local
   _tlocals = local()
   class ThreadLocalMiddleware(object):

   _tlocals.request = request
   def get_tls_request():
