Web Traffic Debugging

Background

More and more desktop or server applications connect to the Internet. For end users, it is sometimes interesting to know what data is being sent from their computer and received by those applications. For programmers, it is key to understand this as well, and they will typically need to drill into the details of all messages being shared, whatever the format. For both needs a tool that can sniff the data being transferred over http and, ideally, https as well, is what is needed.

Recommendation

There is one outstanding tool in this area and this is Fiddler. It notably can work fine with https traffic as well as http traffic of course, and really allows you to dig into every bit of data being transmitted between your computer and the Internet.
