ASP — Session Object

Session Properties

<%
' Session ID
Response.Write(Session.SessionID)

' Timeout in minutes
Session.Timeout = 30

' Abandon session
Session.Abandon
%>

Session Data

<%
' Store data
Session("username") = "John"
Session("loginTime") = Now
Session("preferences") = Array("dark", "large")

' Retrieve data
Response.Write("Hello, " & Session("username"))
%>

Session Events

<!-- Global.asa -->
<SCRIPT LANGUAGE="VBScript" RUNAT="Server">
Sub Session_OnStart
    Session("startTime") = Now
End Sub

Sub Session_OnEnd
    ' Cleanup code here
End Sub
</SCRIPT>

Check Session

<%
If Session("username") <> "" Then
    Response.Write("Logged in as: " & Session("username"))
Else
    Response.Redirect("login.asp")
End If
%>
