HTTP Authentication Extensions for Interactive Clients
Abstract
This document specifies extensions for the HTTP authentication
framework for interactive clients. Currently, fundamental features
of HTTP-level authentication are insufficient for complex
requirements of various Web-based applications. This forces these
applications to implement their own authentication frameworks by
means such as HTML forms, which becomes one of the hurdles against
introducing secure authentication mechanisms handled jointly by
servers and user agents. The extended framework fills gaps between
Web application requirements and HTTP authentication provisions to
solve the above problems, while maintaining compatibility with
existing Web and non-Web uses of HTTP authentication.
