I am using the Response.Redirect method with a URL that passes login info in the URL string. When I arrive at the destination site, instead of logging in automatically, I am prompted for ID & password. (The full querystring has been successfully passed.) If I "cancel" the login prompt and hit the browser's "Go" button, I'm logged in. If I copy & paste the URL into a new browser, I get in no problem. I only get the login prompt when using the Response.Redirect method. Any ideas?
