About HTTP Header Analysis

Header Categories

  • Security: Headers that protect against common web vulnerabilities (CSP, HSTS, X-Frame-Options, etc.)
  • Cache: Headers controlling caching behavior (Cache-Control, ETag, Expires, etc.)
  • Content: Headers describing the response content (Content-Type, Content-Encoding, etc.)
  • General: Standard HTTP headers (Date, Server, Connection, etc.)

Security Score

The security score (0-100%) is calculated based on the presence and configuration of important security headers. Implement all recommended security headers for a better score.
