Windows Service to monitor HTTP requests

[AndrewBuchan]

Hello.

I developed a Console application which monitored HTTP requests using the third party component called Fiddler (fiddlerCore). This works as expected.

I need to convert this functionality into a Windows Service. The code is the same as the console application except for that it is in a Windows Service.

I can install the service and start it correctly but none of the events which monitor HTTP requests are executed.

I am wondering if it is to do with any of the following:

1. Can Windows Services monitor HTTP requests?
2. After the Onstart method has finished executing can events still be triggered?

Here is the Onstart code of my service

			try
			{

                Fiddler.FiddlerApplication.OnNotification += delegate(object sender, NotificationEventArgs oNEA) {
                    EventLog.WriteEntry("App", "Notification " + oNEA.NotifyString);
                };
                Fiddler.FiddlerApplication.Log.OnLogString += delegate(object sender, LogEventArgs oLEA) {
                    EventLog.WriteEntry("App", "logstring " + oLEA.LogString);
                };

                Fiddler.FiddlerApplication.BeforeRequest += delegate(Fiddler.Session oS)
                {
                    EventLog.WriteEntry("App", oS.fullUrl);
                };

                Fiddler.FiddlerApplication.BeforeResponse += delegate(Fiddler.Session oS)
                {
                    EventLog.WriteEntry("App", "before response " + oS.url);
                };

                Fiddler.FiddlerApplication.AfterSessionComplete += delegate(Fiddler.Session oS) {
                    EventLog.WriteEntry("App", "finished session " + oS.url);
                };

                Fiddler.CONFIG.IgnoreServerCertErrors = false;
                FiddlerApplication.Startup(8877, FiddlerCoreStartupFlags.MonitorAllConnections);
                EventLog.WriteEntry("App", "Started service");

            }
            catch (Exception ex)
            {
                EventLog.WriteEntry("App", ex.ToString());
            }

The BeforeRequest and BeforeResponse never get executed/called, whereas the very same code in a console application Main() method does.

Does anyone know what I am missing?


Thanks,
Andrew
