Previous Basic Auth clarified

Hi All I think I missed a bit to my Basic Auth issue which I hope to clarify here. 1) User successfully logins into my UNIX/Apache/Php site using my MySql/SESSION/$_POST combo. 2) Now I need to send a username:password pair to a Windows box to allow access to a Basic Auth protected resource on the Win box. 3) The aim is to seamlessly pass the u:p pair to the win box for auth and allow my user to access the resource. I thought that after doing my checking than sending the u:p pair like this: http://username:password@http://10.0.0.1/dir in a similar fashion to browser ftping would do the trick but it doesn't . Can anyone help me with this please. Server 1 = FreeBSD/Apache1.3/PHP.4.3 Server 2 = Win2K Server Thanks in advance for any help Dave C --- Outgoing mail is certified Virus Free.
