updateOrCreateFromFields is made to call updateOrCreateFromKeyName. updateOrCreateFromFields called self._model.get_or_insert which only creates new entities but doesn't update the properties if the entity already exists. So updateOrCreateFromFields is now made to call updateOrCreateFromKeyName which actually updates the entity properties if entity already exists. Reviewed by: Lennard de Rijk

"""
Pages in Django can are served up with custom HTTP headers containing useful
information about those pages -- namely, the content type and object ID.

This module contains utility functions for retrieving and doing interesting
things with these special "X-Headers" (so called because the HTTP spec demands
that custom headers are prefixed with "X-").

Next time you're at slashdot.org, watch out for X-Fry and X-Bender. :)
