using System.Web;
using System.Messaging;
namespace IISWatcher
{
public class WatchRequests : IHttpModule
{
public void Init(System.Web.HttpApplication app)
{
app.BeginRequest += new EventHandler(app_BeginRequest);

}
void app_EndRequest(object sender, EventArgs e)

System.Diagnostics.EventLog.WriteEntry("HttpModule",
"IpAddress: " + strAddress + strReturn + "URL:" + strUrl);
System.Messaging.MessageQueue msq = new MessageQueue(@".\private$\HttpModuleQueue");

}
public void Dispose()
