Fiddler

Fiddler is an incredibly powerful and useful tool for debugging and testing web applications. It allows developers to easily set stop and access points, view request and response headers, work with incoming and outgoing data, and view cookie data and parameters that are transmitted to the server. The AutoResponder feature is particularly useful, allowing developers to replace server scripts with their local scripts to simplify editing and debugging. Highly recommended for any web developer.
