I am able to restrict access to pages using basic authentication with the
ASP script like this below: The rest of the script is set up to athenticate
using a cookie if it is available.

strAUTH = Request.ServerVariables( "HTTP_AUTHORIZATION" )
if strAUTH = "" then
Response.Status = "401 Not Authorized"
Response.Addheader "WWW-Authenticate", "BASIC realm=""domain.com"""
end if

I have yet been able to find any way of allowing the user to logoff without
using a cookie. I have seen examples done in PHP of how to Logoff a user
but not for ASP.
