Fiddler is a web debugger tool. It logs all web traffic (
https) between your browser and a server. You can use it to inspect the requests and responses between your browser and any web application. For the purpose of this recipe, we will be focusing our attention on the communication between Internet Explorer and our Dynamics CRM server. You can use Fiddler even when using a development machine running Dynamics CRM.
Other advantages of using Fiddler include the ability to set breakpoints and obtain details surrounding performance issues.
To begin this recipe, we need a Dynamics CRM server, a user account on Dynamics CRM, as well as Fiddler installed.
You can download Fiddler from the web for free at
