Session Timeout Logout
From Logic Wiki
Simply I Added a parameter in web.config file This parameter keeps 10 minutes session time
<appSettings>
<add key="SessionTimeOut" value="10"/>
In master page I Add this on top of everything
Basically I check Time variable and if it's null it means nobody logged in yet. timer starts with the login as explained in last code block.
If Time has value I check it against current time and check the difference. If it's more then 10 minutes I remove session variable and send user to logout page (as logout page is doing propoer signouts)
Otherwise I refresh Time with current time
if (Session["Time"] != null)
{
if (DateTime.Now.Subtract(Convert.ToDateTime(Session["Time"])).Minutes > Convert.ToInt32(ConfigurationManager.AppSettings["SessionTimeOut"]))
{
Session.Remove("Time");
Response.Redirect("/signout");
}
else
{
Session["Time"] = DateTime.Now;
}
}
during login I create Time variable
Session["Time"] = DateTime.Now;
