wheh the user logon on my forum and closed the browser, when they try to use the forum they must logon again. I mean that I would like that the user must not logon again.
If they don't have cookies enabled on their browser, there's nothing you can do.
Otherwise, they need to check the "Save Password" checkbox to set the cookie. Its also worth noting that if the cookie expires before they return, they will still be prompted for a login again.
Lastly, if you are working on an intranet you really ought to consider using the NT Login or modifying the NT Login code to work with whatever internal authentication system you are using. (It can fairly easily be changed to work with most systems that support LDAP.)
The cookies are enabled and the "Save Password" checkbox is setted.
If I go to another forum , I can go in without logon (after the first time), but if I try to go in my forum, I must logon each time.... I don't understad why.......
