=head1 NAME |
|
|
|
Apache::lonacc - Cookie Based Access Handler for Construction Area |
|
|
|
=head1 SYNOPSIS |
|
|
|
Invoked (for various locations) by /etc/httpd/conf/loncapa_apache.conf: |
|
|
|
PerlAccessHandler Apache::loncacc |
|
|
|
=head1 INTRODUCTION |
|
|
|
This module enables cookie based authentication for construction area |
|
and is used to control access for three (essentially equivalent) URIs. |
|
|
|
<LocationMatch "^/priv.*"> |
|
<LocationMatch "^/\~.*"> |
|
<LocationMatch "^/\~.*/$"> |
|
|
|
Whenever the client sends the cookie back to the server, |
|
if the cookie is missing or invalid, the user is re-challenged |
|
for login information. |
|
