Why are security headers like HSTS and CSP important?

Security headers instruct the browser to enforce strict HTTPS encryption (Strict-Transport-Security), prevent clickjacking attacks (X-Frame-Options), and block Cross-Site Scripting (Content-Security-Policy).

How do I check if my website has a 301 redirect chain?

Enter your URL. If the server issues a 301 or 302 redirect, our tool displays every intermediate hop along with the final status code (200 OK), helping you eliminate crawl-budget-wasting redirect chains.

What does the 'Server' or 'CF-Cache-Status' header indicate?

The 'Server' header identifies the web server software (e.g. cloudflare, nginx, Apache), while 'CF-Cache-Status' (HIT, MISS, BYPASS) indicates whether Cloudflare CDN served the asset from its edge cache.

Frequently Asked Questions

HTTP response headers are metadata key-value pairs sent by a web server to the client's browser before delivering the page content. They communicate status codes, caching instructions, content types, and security policies.
