Frequently Asked Questions

Why should I check HTTP headers?

Headers reveal caching behavior, security policies (CSP, HSTS), CORS settings, compression, and whether redirects are set up properly.

What is the X-Frame-Options header?

X-Frame-Options prevents your site from being embedded in iframes on other sites, protecting against clickjacking attacks.
