Fiddler started as Eric Lawrence’s side project back in 2003. Fiddler is a free web debugging proxy that runs on your own machine and allows you to monitor, inspect, and modify all traffic between your computer and the internet. Fiddler has become an essential tool for web developers of all skill levels.
Fiddler can be used to debug web applications or services, understand how a website or service works, or test web application security. Fiddler can also be used to debug mobile applications that use web services by proxying traffic from the device to Fiddler running on the development machine.
Fiddler Everywhere is the next generation of Fiddler. Fiddler Everywhere is a cross-platform web debugging proxy that runs on Windows, macOS, and Linux. In this video, I’ll give you a sneak peek of my Pluralsight course, Fiddler Everywhere 3: The Big Picture.
The full course is available now, and it’s free with a Pluralsight membership. Use the following link to access it:

Debugging web traffic is an essential skill for any web developer or IT professional. Being able to identify and fix issues with web traffic can improve the performance and functionality of websites, applications, and servers. In this article, we will discuss some tips and techniques to help you debug web traffic like a pro.
One of the first steps in debugging web traffic is to use a tool like Wireshark. Wireshark is a powerful network protocol analyzer that allows you to capture and interactively browse the traffic running on a computer network. With Wireshark, you can see the data flowing between your computer and the web server, as well as any issues or errors that may be occurring.
Another useful tool for debugging web traffic is Fiddler. Fiddler is a free web debugging tool that allows you to inspect and modify the HTTP traffic between your computer and the internet. With Fiddler, you can see detailed information about each HTTP request and response, including headers, cookies, and payloads.
In addition to using tools like Wireshark and Fiddler, there are several other techniques you can use to debug web traffic. One common technique is to use browser developer tools. Most web browsers have built-in developer tools that allow you to inspect and debug web traffic in real-time. With browser developer tools, you can see detailed information about the network requests your browser is making, as well as any errors or warnings that may be occurring.
Another useful technique for debugging web traffic is to enable logging on your web server. By enabling logging on your server, you can see detailed information about the requests and responses that are occurring, as well as any errors or issues that may be occurring. By reviewing server logs, you can quickly identify and troubleshoot any issues with your web traffic.
It’s also important to understand the different types of web traffic that can occur. For example, HTTP traffic is used for most web browsing, while HTTPS traffic is used for secure transactions like online banking or shopping. By understanding the different types of web traffic, you can better diagnose and fix any issues that may be occurring.
In addition to tools and techniques, it’s important to have a good understanding of web protocols and technologies. By understanding how web traffic works, you can better diagnose and fix any issues that may be occurring. For example, if you are experiencing slow loading times on your website, you may need to optimize images or minify CSS and JavaScript files to improve performance.
In conclusion, debugging web traffic is an essential skill for any web developer or IT professional. By using tools like Wireshark and Fiddler, as well as techniques like browser developer tools and server logging, you can quickly identify and fix issues with your web traffic. By understanding web protocols and technologies, you can better diagnose and troubleshoot any issues that may be occurring.Debugging web traffic may seem like a daunting task, but with the right tools and techniques, you can easily debug web traffic like a pro. By using tools like Wireshark, Fiddler, browser developer tools, and server logging, as well as having a good understanding of web protocols and technologies, you can quickly identify and fix any issues with your web traffic. So don’t let web traffic issues slow you down – start debugging like a pro today!
