For example, if you are sending a request to a web service and receiving a response that is inaccurate, you can examine the SOAP packet directly using a TCP trace utility.
TCP trace utilities can be used on the client and on the server. If your local machine is acting as client and server during debugging, you can open up two different sessions in the TCP trace utility and examine the requests and responses to HTTP requests.
We examine some of the popular TCP trace utilities in the following sections.
