        !            41: 
        !            42: This module enables cookie based authentication and is used
        !            43: to control access for many different LON-CAPA URIs.
        !            44: 
        !            45: Whenever the client sends the cookie back to the server, 
        !            46: this cookie is handled by either lonacc.pm or loncacc.pm
        !            47: (see srm.conf for what is invoked when).  If
        !            48: the cookie is missing or invalid, the user is re-challenged
        !            49: for login information.
