//The global.asax file in Listing 3.8 contains event handlers for the Session and Application objects. Each event handler has the same signature as the Page_Load event handler.
//The code in Listing 3.8 handles three Application object-related events: Start (Lines 3-8), End (Lines 24-30), and BeginRequest (Lines 11-16). Start and End are called when the Web application starts and ends, respectively. BeginRequest is called for every page hit that the site receives. Listing 3.8 updates the total number of hits on this event.
//The Session Start (Lines 17-22) and End (Lines 24-30) events are handled in the middle of the listing. These two events count how many different Web users have accessed the site.
//You can write a simple page to utilize the statistics that Listing 3.8 tracks. Listing 3.9 shows a page that writes out the results of the hit-counting code
