HTTP Headers Parser

HTTP Headers Parser

🌐 What Is an HTTP Headers Parser?

An HTTP Headers Parser is a tool that helps developers and website owners view, analyze, and debug the HTTP headers exchanged between a client (browser) and server during a web request.

It reveals essential metadata such as:

• Server type (Apache, Nginx, etc.)
• Content type (HTML, JSON, etc.)
• Caching behavior
• Redirects (301/302)
• Security headers (HSTS, CSP, etc.)
• Cookies
• User-agent info
• HTTP status codes (e.g., 200, 404, 500)

This tool helps:

• 🧑‍💻 Developers optimize sites
• 🔐 Security teams audit configurations
• 🧠 SEO professionals detect redirect chains
• 📦 API users test endpoints

🚀 Why Use It?

• ✅ Identify HTTP response issues
• ✅ Debug REST API responses
• ✅ Detect multiple redirects or missing headers
• ✅ View server and content negotiation behavior
• ✅ Check if security headers are present
• ✅ Improve SEO and loading speed

🛠️ How It Works

1. Enter a URL (e.g., https://example.com)
2. Click “Parse Headers”
3. The tool fetches the HTTP response and displays:
   • Request headers sent by the tool
   • Response headers received from the server

✅ You’ll also see:

• HTTP version (1.1, 2.0, etc.)
• Status code explanation
• Header categories (security, cache, cookies…)

📋 Sample Output
