HEAD
- Support Apache 2.4
- PerlAuthenHandler needs to set $r->user() for requests for <Location>
directives which include Require valid-user
- reverse changes in publiccheck.pm rev. 1.20 and 1.21
- modify changes in lonacc.pm rev. 1.143 and 1.147
- reverse changes in lonnet.pm rev. 1.1212 and 1.1213, and modify changes
in rev. 1.1244 (no longer treating 2.4 as a special case).
- Apache access logs will now include username (or username:domain if user's
domain is not server's default domain) for URLs requiring "valid-user",
- Apache access logs will now include 'public' as requester for image
files from /res/adm/pages and also domain logos etc.

30: =head1 NAME
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.
