Hi everybody,

In our master page I see the following code

private void LoadExpiresScript()
    {
        FormsAuthenticationTicket Athen = (FormsAuthenticationTicket)((FormsIdentity)this.Page.User.Identity).Ticket;

        if (!Athen.IsPersistent)
        {
            //Athen.Expiration = DateTime.Now.AddHours(12);
            TimeSpan TimeLeft = Athen.Expiration - DateTime.Now;
            double TimeOutMil = TimeLeft.TotalMilliseconds - 10000;

          
            this.Page.ClientScript.RegisterStartupScript(this.GetType(), "AuthenticationTimeOut",
                @"var defaultTimeOutMilliseconds = " + Convert.ToInt32(TimeOutMil).ToString() + @";
      
var TimeOutId;

    setupTimeout(defaultTimeOutMilliseconds);

function displayAlert(){alert(""As a security precaution, your Friendship Circle Administration session is about to end. Due to inactivity."");
top.location=""" + FormsAuthentication.LoginUrl + "?ReturnUrl=" + Server.UrlEncode(Request.Url.PathAndQuery) +
            @""";
setupTimeout(defaultTimeOutMilliseconds);
}
function setupTimeout(timeOutMilliseconds)
{
    TimeOutId = window.setTimeout('displayAlert()', timeOutMilliseconds);
}
function ResetTimeOut()
{
    window.clearTimeout(TimeOutId);
    setupTimeout(defaultTimeOutMilliseconds);
}", true);
        }
    }

When I was testing it I noticed that the Expiration time was set for ~30 minutes after I started my session. I'm guessing it's some default setting. How and where can I adjust it and what are the consequences of making this time bigger?

Thanks in advance.
