Inspect the exact HTTP headers your browser sends to our server
ABOUT_HTTP_HEADERS
HTTP headers are metadata sent with every web request. They contain information about your browser, accepted formats, security tokens, and more. Websites use these headers to customize responses and track users.
What are HTTP headers used for?
HTTP headers carry metadata about requests and responses. They specify content types, caching rules, authentication, cookies, and security policies between browser and server.
What are security headers?
Security headers like Sec-Fetch-* and Sec-CH-* provide information about request context and client hints. They help servers make decisions about cross-origin requests and client capabilities.
Can headers be used to track me?
Yes. Headers like User-Agent, Accept-Language, and Accept-Encoding reveal information about your browser. Combined with other data points, they can contribute to browser fingerprinting.
