Depending on what OS you're using and what specific info you need, you might look at TCPView or Wireshark.
there are several tools available for this some free , some not - as mentioned Wireshark is a great free tool - but most network capture tools are hard to read and understand unless you know whta you are looking at - as for being able to stop or edit whats being sent - thats dependent on the application and its settings -
there are also browser plugins;
and the net had a large list of proxy software that was able to trace passing requests into logs and allow to cease.. actually cant remember the url but there are lots of such little projects, and you can write your own proxy.
There is a small program called Active Ports
for Win32, which lists the ports in use with application name.
