HTTP Header Analyzer
Description
Input Headers
Paste HTTP headers here (one per line, format: Header-Name: value)
❓What is HTTP Header Analysis
HTTP header analysis is the process of examining HTTP response headers to assess website security and performance. Security headers protect against attacks like XSS, clickjacking, and MIME sniffing. Performance headers optimize caching and compression. Analyzing headers helps identify missing security measures, misconfigurations, and performance optimization opportunities. Regular header audits are essential for maintaining secure and fast websites.

Application Scenarios
🔒
Security Audit & Compliance
Security teams, DevOps engineers, and compliance officers need to audit HTTP headers to ensure websites meet security standards (OWASP, PCI-DSS, GDPR). Regular header analysis helps identify missing security headers, verify CSP configurations, and ensure HSTS is properly implemented for compliance audits and security certifications.
🌐
Website Security Hardening
Web developers and system administrators need to harden website security by configuring proper HTTP security headers. Analyzing headers helps identify vulnerabilities, configure CSP policies to prevent XSS attacks, set up HSTS for HTTPS enforcement, and implement clickjacking protection before deploying to production.
⚡
Performance Optimization
Frontend developers and performance engineers need to optimize website loading speed by analyzing cache headers, compression settings, and ETag configurations. Header analysis helps identify missing Cache-Control directives, verify Content-Encoding settings, and optimize caching strategies to improve page load times and reduce server load.
🔍
Pre-deployment Testing
QA teams and developers need to verify HTTP header configurations before deploying applications to production. Header analysis helps catch misconfigurations, missing security headers, and performance issues during staging and pre-production testing, ensuring applications meet security and performance requirements before going live.
📋Usage Guide
Step 1
Copy HTTP headers from browser DevTools or server response
Step 2
Paste headers into the input area (one per line)
Step 3

📚Technical Introduction
🔒Security Headers
Security headers are HTTP response headers that help protect websites from various attacks. Content-Security-Policy (CSP) prevents XSS attacks by controlling resource loading. Strict-Transport-Security (HSTS) forces HTTPS connections. X-Frame-Options prevents clickjacking. X-Content-Type-Options prevents MIME sniffing. Referrer-Policy controls referrer information leakage. These headers are essential for modern web security.
⚡Performance Headers
Performance headers optimize website loading speed and reduce server load. Cache-Control specifies caching directives for browsers and proxies. ETag enables efficient cache validation without re-downloading unchanged resources. Content-Encoding indicates compression (gzip, brotli) reducing transfer size. Proper configuration of these headers can significantly improve page load times and reduce bandwidth usage.
📊Header Analysis
HTTP header analysis involves checking presence, values, and configuration of security and performance headers. Tools analyze headers against best practices and security standards like OWASP recommendations. Missing security headers indicate vulnerabilities. Misconfigured headers can cause security issues or performance problems. Regular header audits help maintain website security and performance.
