31:
32: Apache::lonacc - Cookie Based Access Handler
33:
34: =head1 SYNOPSIS
35:
36: Invoked (for various locations) by /etc/httpd/conf/srm.conf:
37:
38: PerlAccessHandler Apache::lonacc
39:
40: =head1 INTRODUCTION
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.
50:
51: This is part of the LearningOnline Network with CAPA project
52: described at http://www.lon-capa.org.
