سرآیندهای HTTP

Every HTTP response starts with headers: the status code, the content type, caching rules, cookies and — increasingly — security policies. This tool requests a public URL once, reads the headers and closes the connection without downloading the body. Redirects are shown, not followed, so you can inspect each step yourself.

The security-header overview checks for the usual browser protections: HSTS (HTTPS only), Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, Referrer-Policy, Permissions-Policy and Cross-Origin-Opener-Policy. A missing header is not automatically a vulnerability; it means the browser falls back to its default behaviour.

Below, you also see the request headers your own browser sent to load this page.
