In short, you will need to add a lot of logs to the area of ββcode, which behaves strangely to give you hints as to what is happening on the server.
If the web service runs on ASP.NET, you can use the built-in log by enabling tracing in your Web.config and then running the following command: HttpContext.Current.Trace.Write("hello"); . Then all HTTP requests and user logging can be viewed by going to http: //host/Trace.axd
If you are not using ASP.NET, you can use a library like log4net, or flip your own.
