Hi I'm planning to use Digest Authentication. It's not however still clear to me yet how to forward the credential information. A redirector redirects the user to a local web page. This page should provide an interface for authentication right? Once the user enters the username and password on the html form how do I forward the credential? Do I just use get or post method in the html form? I read from squid the definite guide that when using digest the password doesn't get sent in the http request but rather a digest message get sent with the username. I don't exactly understand where the digest on the client machine gets calculated. Is it the HTTP protocol that does it? Sorry for bugging you with these questions that might be quite stupid but I'm trying to figure these things out. Any help or suggestion on where to look for information on how to implement digest is very appreciated. I'm looking at HTTP: the Definite guide, Squid: the definite guide but I didn't fully get how to implement it. Thank you very much for your help. Rocco
