C# Clear Session

Question #1

I want to know when am I supposed to use:

Session.Abandon() // When I use this during tracing and after calling it- I find the session still has a value.

And when am I supposed to use :

Session.Clear()

When should I use each specific method?

• In general?
• In my specific case?

I check if session is not equal null in Page Load. If session is equal to null, I wanna to clear session and redirect to the login page?

Should I use something like this:

private void initSession()
{
    Session.Clear();
    Session.Abandon();
    Response.Redirect("LoginPage.aspx");
}
