This exception is util when you want to raise an exception but want its message be shown as a message to the user, with no error 500 or 404 pages.
To use it, just append the middleware in the MIDDLEWARE_CLASSES setting and raises HttpMessage when necessary.

This recipe catches all errors. "except HttpMessage" is missing in process_exception().
