 Site credentials are normally restricted very strictly to
 browser->website communication and the proxy does not take part.

 That said, for specific site(s) you can configure an explicit
 originserver cache_peer link to the web server. Using the login= option
 to send credentials for all requests down that link.

 These are restricted to insecure Basic auth credentials in all squid.
 Latest releases extend this to include Negotiate/Kerberos auth as
 mentioned in that doc.

 NOTE that in any event the user is never actually authenticated. What
 goes down the link may in fact be multiple interleaved "users" on the
 receiving side of Squid. The only thing that type of auth validates is
 that the request came through your Squid. Be careful.
