Give an example of how to use Application and Session events?-interview04032012

To see how Application and Session events occur, add the following code to the Global.asax file in a Web forms project. void Application_Start(object sender, EventArgs e) { // Create Application state variables. Application["AppCount"] = 0; Application["SessCount"] = 0; // Record application start. Application["AppCount"] = (int)Application["AppCount"] + 1; } void Session_Start(object sender, EventArgs e) { // Count sessions. Application["SessCount"] = (int)Application["SessCount"] + 1; } void Session_End(object sender, EventArgs e) { // Decrement sessions. Application["SessCount"] = (int)Application["SessCount"] - 1; } Add the following code to WebForm1.aspx file in a Web forms project and set WebForm1 as start up page. protected void Page_Load(object sender, EventArgs e) { // Display Application count. Response.Write("Number of applications: " + Application["AppCount"] + " "); // Display session count. Response.Write("Number of sessions: " + Application["SessCount"] + " "); } To demonstrate the events, run the preceding code, and then start a new instance of the browser and navigate to the address. Each new instance of the browser increments the session count, but the application count stays at 1.
