if it is the webwiz database login script you are talking about, you find all the info you need in the ReadMe.txt file.. but if you have problems with reading it you can add this code to the pages you want to protect:
<%
'If the session variable is False or does not exsist then redirect the user to the unauthorised user page
If Session("blnIsUserGood") = False or IsNull(Session("blnIsUserGood")) = True then
'Redirect to unathorised user page
Response.Redirect"unauthorised_user_page.htm"
End If
%>
the pages have to be in the same directory as your login script or you have to change the path and name of the unauthorised user page
