HTTP Debugging

HTTP debugging is the process of inspecting, analyzing, and troubleshooting HTTP requests and responses between clients (e.g., web browsers, mobile apps) and servers. It involves using specialized tools to capture, log, and examine network traffic to identify issues like errors, performance bottlenecks, or security vulnerabilities. This skill is essential for developers working with web applications, APIs, and networked systems to ensure proper communication and functionality.

Also known as: HTTP Debug, HTTP Traffic Inspection, Network Debugging, Web Debugging, HTTP Sniffing

Why learn HTTP Debugging?

Developers should learn HTTP debugging when building or maintaining web-based applications, APIs, or microservices to diagnose issues such as failed requests, slow responses, or incorrect data transmission. It is crucial for debugging in development environments, testing API integrations, and optimizing performance in production systems, as it provides visibility into the underlying network interactions that drive modern software.
