AuthCookieURL.pm  view on Meta::CPAN

few months without problem.  The interface may change (or disappear) without notice.
Please report any problems or comments back to Bill Moseley E<lt>moseley@hank.orgE<gt>.

This module is a modification of Ken Williams E<lt>ken@forum.swarthmore.eduE<gt> Apache::AuthCookie.
Please see perldoc Apache::AuthCookie for complete instructions.  As this is intended to be
a drop-in replacement for Apache::AuthCookie you may wish to install and test with Ken's
Apache::AuthCookie before trying AuthCookieURL.

Basically, this module allows you to catch any unauthenticated access and redirect to a
login script that you define.  The login script posts credentials (e.g. username and password)
and your module can then validate and provide a session key.  The session key is sent in a cookie,
and also in a munged URL and a redirect is issued and the process starts all over.

Typically, you will write your own module that will override methods in Apache::AuthCookieURL.
These methods are described completely in Ken's Apache::AuthCookie.  Your methods will be used
to generate and validate session keys.  You can use Apache::AuthCookieURL without overriding
its methods and then AuthCookieURL can be used as a simple session manager.

With this module you should be able to enable session management for an entire site
using E<lt>Location /E<gt>, and then allow access to, say, the images directory, and also require
password access to other locations.  One issue at this point is that the session key is
stripped from URLs in a Trans handler.  So you would need to use cookies to use different
session keys for different parts of your web tree.

Apache::AuthCookieURL adds the following features to Apache::AuthCookie.

not acceptable then you can return a list, with the second element being an error message
that is placed in a cookie.  This allows your login script to display a failure reason.  This
method is needed since a redirect is done before your login script is executed again.  Of course,
this requires that the client has cookies enabled.

Another method is to return a session key that is really an error code and generate
messages based on that returned session (error) code.

=item * authen_ses_key()

This method's job is to validate and convert a session key into a username and return it.
AuthCookieURL places the returned value into $ENV{REMOTE_USER}.
