HTTP Header Checker

What is the HTTP Header Checker?

The HTTP Header Checker is a diagnostic tool designed to retrieve and display the HTTP response headers returned by a web server. It provides visibility into server status codes, caching policies, content types, and security headers (like HSTS and CSP). This tool is critical for SEO professionals and developers looking to verify redirection chains, debug server configurations, and improve website security.
