Hello:
I don't know, how to logoff a user who is currently logged in.Please can anyone send me a logoff script.Please help me as soon as possible.
Thank You.

logoff.asp
<%
Session.Abandon
Response.Redirect("login.asp")
%>

Thanks for your help:
I did what you said.
the user can logoff but still can access the resticted pages.
can you help me.

User can access the restricted pages...even after closing their browser..?

put a session variable during the login authentication..check for that session variable on all of your restricted pages otherwise redirect them to the login page...
when you log off clear that session varibale so if users try to access your restriced pages they will be redirected to the login page..

Hello:
Thanks for your help.
I still don't know what you mean by session variable and how to put it and clear it.
Please can you send me the script that i have to put on every page so the user won't be able to access the restricted pages after logging off.
Thank You.

on your checklogin page

<%
'Logic for checking your username and password
'if username and password matches initialize a session variable

Session.Contents("UserOK") = "Yes"
%>

on all of your restricted pages put this code before anything else
<%
IF Session.Contents("UserOK") <> "Yes" Then
  Response.Redirect("login.asp")
End IF
%>

on your logoff script clear this session variable using Session.Abandon

If all of the above does not make sense, Grab an ASP book and read on session variables.
