Understanding the Role of HTTP Headers

When your web browser communicates with a web server, it does so by sending and receiving HTTP Headers. These headers are crucial pieces of metadata that contain vital instructions about the request and the server's response. They are invisible to the average user but are the backbone of web performance, security, and caching mechanisms.

For developers and system administrators, parsing these headers is essential for:

• Troubleshooting: Diagnosing why a page is loading slowly, displaying errors, or not caching properly.
• Security Audits: Checking for critical security headers like `Content-Security-Policy` and `Strict-Transport-Security`.
• SEO & Caching: Analyzing headers like `Cache-Control`, `Expires`, and Status Codes (e.g., 301, 404, 200 OK) to ensure proper search engine indexing.
