Frequently Asked Questions

What is the purpose of HTTP headers?

HTTP headers provide metadata about the request or response. They contain information about content type, caching, security, cookies, and server configuration.

Why check HTTP headers for security?

Missing security headers indicate potential vulnerabilities. Checking headers helps identify if a site has implemented important protections against common attacks.

Can websites hide their server information?

Yes, administrators can remove or obscure the Server header. However, fingerprinting tools can still identify servers through other methods and response patterns.
