namespace SRTT_HEALTH
{
    public class Global : System.Web.HttpApplication
    {

        protected void Application_Start(object sender, EventArgs e)
        {
            // Code that runs on application startup
            Application["Visitors"] = 0;
         
        }

        protected void Session_Start(object sender, EventArgs e)
        {
            // Code that runs when a new session is started
            Application.Lock();
            Application["Visitors"] = Convert.ToInt32(Application["Visitors"]) + 1;
            int users = Convert.ToInt32(Application["Visitors"]);
            Application.UnLock();
         
        }

        protected void Application_BeginRequest(object sender, EventArgs e)
        {

        }

        protected void Application_AuthenticateRequest(object sender, EventArgs e)
        {

        }

        protected void Application_Error(object sender, EventArgs e)
        {
         
        }

        {

        }

        protected void Application_End(object sender, EventArgs e)
