Careful! Try it out with the wrong information first, once you've set the cookie using the right information, it will always take you to the protected page (in this case 'glob.htm', if available, page not found, if not) without prompting. In this example the username is 'Fred' and the password is 'glob'. Configuring a different name/password combo is still done as described here. The cookie expiration can be set in the cookie code (Hint, set it to one (1) or zero (0) at first, in case you decide to change passwords, as once the cookie is set, it makes no difference what the password/username is):

Also, you can always delete cookies to start over, but your users may not know that so, get it worked out locally before going live.
