HTTP Headers Checker FAQ
Why is the Server header hidden?
Many websites deliberately remove or minimise it to avoid exposing unnecessary software details.
Does missing a security header prove a site is unsafe?
No. It indicates a possible hardening opportunity, but security depends on the full application and infrastructure.
Why can the result differ from my browser?
The server may respond differently by location, user agent, cookies, caching layer or request method.
