Fiddler is a freeware developed by Eric Lawrence. This tool is used to debug HTTP traffic from any application including Internet Explorer, Firefox, and other browsers. From the Fiddler's website, the description of Fiddler is as follows:
Fiddler is a Web Debugging Proxy which logs all HTTP(S) traffic between your computer and the Internet. Fiddler allows you to inspect all HTTP(S) traffic, set breakpoints, and fiddle with incoming or outgoing data. Fiddler includes a powerful event-based scripting subsystem, and can be extended using any .NET language.
In this recipe, we will use Fiddler to get a result as a JSON response.
Fiddler needs to be installed and configured properly. If you do not have Fiddler, you can get this freeware from: http://www.Fiddler2.com. The installation of this tool is pretty easy, and all the needed documentation is available on the site.
