TCP Spy 2.13

TCP Spy will capture and display all socket calls that an application makes and the data that is sent and received on the applications sockets. TCP Spy will work with any type of application.
TCP Spy can be used by a developer to debug socket communication problems with an application or by anyone who is curious about what socket calls an application is making, including what it is communicating with and the data it is passing
When TCP Spys Start button is pressed, it will capture and display all socket calls of the next application that makes a socket call. It will also capture and display the data that is sent and received on the applications sockets. The application can be of any type.
TCP Spy displays its output in a scrollable text box. This data may additionally be sent to a file. By default, only 32KB of data is kept in the scrollable text box. Higher data limits may be selected, including unlimited.
Based upon each sockets first transferred message, TCP Spy will determine if the protocol being communicated over the socket is text based. If so, TCP Spy will test each following message for text.
If a message contains only text, TCP Spy will display it as such. Else, TCP Spy will show the message in hexadecimal and ASCII. If the protocol is HTTP, the HTTP headers will be displayed as text.
Version restrictions:
- The unregistered version does not provide the option of sending data to a file, and only keeps 32KB of data in the scrollable text box. When you register TCP Spy, you will be sent a code that enables the additional features.
