HTTP Header Parser

HTTP Headers Parser helps developers inspect and understand the metadata sent by web servers in HTTP responses. Headers contain critical information about caching, security policies, content encoding, cookies, server configuration, and more. This tool fetches real HTTP headers from any URL and organizes them by category for easy analysis.

Key Features

• •Security Analysis: Automated security header audit with grading system (A-F)
• •Performance Insights: Analyze caching, compression, and CDN configuration
• •Category Organization: Headers grouped by Security, Caching, CORS, Content, and General
• •Multiple Views: Switch between table view and raw JSON output
• •Response Metrics: View status codes, response time, and header count
• •Export Options: Download headers as JSON for documentation

Common Use Cases

• •Security Audit: Check if websites have proper HSTS, CSP, and X-Frame-Options headers
• •API Debugging: Inspect Content-Type, Content-Encoding, and custom headers
• •Cache Analysis: Verify Cache-Control, ETag, and Expires headers
• •CORS Troubleshooting: Check Access-Control headers for API integration
• •CDN Detection: Identify CDN usage through cf-*, x-cache, and server headers
• •Performance Check: Analyze compression headers and response timing
