This is a question of how to properly implement or use web server authentication through squid 2.X. This is not a question about authentication to the Squid server itself. The scenario is: Users --> Squid 2.5 --> IIS6 This is all internal and there is no authentication to the Squid server itself. What authentication schemes are available to use for web applications running on the IIS? - Basic - Forms Based - Digest - Advanced Digest - NTLM (I already know this will not work based on protocol design) - Windows Integrated (I already know this will not work based on protocol design) Any suggestions, examples, or documentation would be greatly appreciated.... -- David
