Our site uses HTML forms authentication at present. We&#039d like to allow our users the option to set a cookie so they don&#039t have to login once they&#039ve done so the first time. Many of our users share a PC, so it&#039s not appropriate to convert to automatic cookie auth for everyone. Many commercial sites have a check box in their login form that lets users opt-in to a persistent cookie. How would you do this with IIS 4?
