For web applications running in a CGI monad container, this module
provides a simple interface to generate HTTP Digest authentication
challenges and to process the responses from clients. It implements
RFC2617, but accepts the quirky responses generated by some
non-compliant browsers.
This module was originally implemented for Serialist
(http://serialist.net) and is deployed there in a FastCGI
environment using the fastcgi package. It has been tested against a
variety of browsers, including Firefox, Safari, IE, Opera, and others.
