using global asax

i'm currently writing to a custom event log in the code behinds but want to switch it over to the global asax file -- just not sure how to do it. I want the global asax to check for the custom event log so each page doesn't have to do it.
//default page code behind

using System.Diagnostics;

public partial class _Default : System.Web.UI.Page
 string sWebAppName = "TestSite";

public string webAppName
 get { return sWebAppName; }
 set { sWebAppName = value; }

protected void Page_Load(object sender, EventArgs e)

//code to generate an error

void checkEventLog()
 if (!EventLog.SourceExists(webAppName)) EventLog.CreateEventSource(webAppName, webAppName);



//how do i use the global asax?

<%@ Import Namespace="System.Diagnostics" %>

<script runat="server">

Application["webAppName"] = "TestSite";

void Application_Start(object sender, EventArgs e) 
 if (!EventLog.SourceExists(webAppName)) EventLog.CreateEventSource(webAppName, webAppName);
