   Apache::lonacc - Cookie Based Access Handler
   
   =head1 SYNOPSIS
   
   Invoked (for various locations) by /etc/httpd/conf/srm.conf:
   
    PerlAccessHandler       Apache::lonacc
   
   =head1 INTRODUCTION
   
   This module enables cookie based authentication and is used
   to control access for many different LON-CAPA URIs.
   
   Whenever the client sends the cookie back to the server, 
   this cookie is handled by either lonacc.pm or loncacc.pm
   (see srm.conf for what is invoked when).  If
   the cookie is missing or invalid, the user is re-challenged
   for login information.
   
   This is part of the LearningOnline Network with CAPA project
   described at http://www.lon-capa.org.
