What Is an HTTP Header Checker?

An HTTP header checker is a tool that requests a URL and displays the response headers returned by the web server. These headers describe status code, content type, cache behavior, redirects, cookies, server details, and security rules.

Website owners, developers, SEO specialists, and security teams use HTTP header checks to debug redirects, verify cache rules, inspect server responses, and identify missing security headers.

Header Type	Purpose	Example
Status	Shows server response result	200 OK, 301 Redirect, 404 Not Found
Location	Shows redirect destination	HTTP to HTTPS redirect
Cache-Control	Controls browser and CDN caching	max-age, no-cache
Content-Type	Shows file or page type	text/html, application/json
Security Headers	Improve browser security	HSTS, CSP, X-Frame-Options
