Frequently Asked Questions
What are HTTP headers?
HTTP headers are additional information sent with HTTP requests and responses. They include metadata like content type, caching directives, security settings, and server information.
What are security headers?
Security headers like Content-Security-Policy (CSP), Strict-Transport-Security (HSTS), and X-Frame-Options help protect websites from various attacks. They should be properly configured.
What is a redirect chain?
A redirect chain occurs when a URL redirects to another URL, which may redirect again. The checker follows these redirects and shows the complete chain with status codes.
Can I check any website?
You can check any publicly accessible website. The tool makes HTTP requests to retrieve headers. Some sites may block automated requests or require specific headers.
