=head1 NAME |
|
|
|
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. |

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. |
