Fiddler Classic 5 Fundamentals from Pluralsight

Fiddler 5 Classic is an application for observing and generating web traffic. This course will teach you how to observe and generate web traffic using Fiddler 5 to develop and troubleshoot web applications.

All non-trivial web applications use a variety of complex techniques that allow users to interact with and authenticate themselves with your app using HTTP and REST. But how do you develop, analyze, and troubleshoot the network requests applications make? In this course, Fiddler 5 Classic Fundamentals, you’ll learn to develop and debug applications by observing and generating web traffic using Fiddler. First, you’ll explore observing traffic with Fiddler, using the Inspector Panel to identify and report bugs. Next, you’ll discover HTTPS Network traffic, and how to use Fiddler to decrypt and analyze it, allowing debugging of many more applications. Finally, you’ll learn how to generate network traffic, allowing Fiddler to be used to develop applications and validate use cases. When you’re finished with this course, you’ll have the skills and knowledge of Fiddler needed to observe, generate, and analyze basic traffic, and integrate with more advanced fiddler workflows with minimal training.

Reviews summary

Essential fiddler classic 5 foundations for web debugging

According to students, this course provides a solid and practical introduction to Fiddler Classic 5, especially for those new to web traffic analysis and debugging. Many learners found the explanations clear and the hands-on demos helpful for understanding how to observe, decrypt HTTPS, and generate traffic. However, some experienced users noted it's primarily for beginners and lacks deeper dives into advanced features or scripting. While the fundamental concepts are well-covered, a few wished for more engaging presentation or less assumed networking knowledge.

Perfect for those starting with Fiddler, but too basic for experienced users.

"Excellent introduction to Fiddler. I had no prior experience, and it walked me through everything."

"A must-have for anyone new to web application debugging and Fiddler."

"Completely redundant if you have any prior experience with Fiddler. The content is too basic."

Teaches skills directly applicable to web development and troubleshooting.

"I can immediately apply this to my work for debugging web applications."

"The practical exercises solidified my understanding of how HTTP/S requests flow."

"I learned how to use practical tools and strategies that I could apply immediately to my work."

Concepts are broken down well with helpful, practical demonstrations.

"The instructor explained complex concepts like HTTPS decryption clearly."

"The hands-on demos were extremely helpful for understanding how to troubleshoot network issues."

"The course is practical and to the point. Concepts are broken down well."

A few sections implicitly assume basic networking understanding.

"My only minor critique is that some explanations assumed a bit of prior networking knowledge."

"I had to supplement with outside documentation to fully grasp certain aspects."

Some found the presentation dry or wished for more real-world scenarios.

"The instructor's pace was too slow for me, and some explanations were verbose."

"The presentation felt a bit dry. I learned new tricks, but it wasn't as engaging."

"Some parts could benefit from more real-world scenarios to keep interest."

Focuses on fundamentals, not advanced Fiddler features or scripting.

"I wish there were more advanced examples or deeper dives into specific Fiddler features."

"For those looking for advanced scripting or integration, this course is just a starting point."

"Could use more in-depth coverage on complex topics or optimization techniques."
