Hi

Even though each Request is supposed to open the file and close it
independently. Could it be possible that one request afftects the second one?

I would really appreciate your help.
Thanks
Alvin

Basically the code looks like this:

Public class Service: System.Web.Services.Webservices
{
    public Service() {
    }
    publicn ServiceRequest()
   {
      fs = File.Open()
      Debug.Listeners.Add(TextWriterTraceListener(fs);
      Debug.Write();
      ...
      ...
      Debug.Write()
      Debug.Flush()
      fs.Flush()
      fs.Close()
   }

}
