Question

When someone logs into my application and they checked the “Remember Me” checkbox, I set the createPersistentCookie = true so that when they come back they don’t need to log in again. However, occassionally, I need to use the FormsAuthentication.SetAuthCookie(NewUserName, [true/false]) so how do I know if they originally set the createPersistentCookie to true or not so I can keep it the same as it was when they logged in?

Answer 1

I believe when you decrypt the cookie you should be left with a FormsAuthenticationTicket which you can then query the IsPersistent property.

To decrypt:

FormsAuthenticationTicket ticket = FormsAuthentication.Decrypt(Request.Cookies[FormsAuthentication.FormsCookieName].Value);
