HTTP Header Generator
Used by developers, writers, and creators worldwide.
An HTTP header generator gives you real request and response headers with valid example values, ready to drop into docs, tests, and learning material. Choose how many you want and it returns a shuffled set — Content-Type, Authorization with a bearer token, Cache-Control, a Set-Cookie with the right security flags, rate-limit and CORS headers. Developers use it to fill in API examples, mock a request in a test, or study what each header actually does without hunting through the spec. Each value follows the correct format, so you can paste it straight into curl, a REST client, or documentation. Pick the headers your scenario needs, swap in your own values, and you have a realistic request or response in seconds. It is faster than remembering the exact casing and syntax of headers you only touch occasionally.

FAQ
are these header values valid
Yes — each follows the correct syntax and casing for its header, so you can paste it into curl, a REST client, or docs and only need to swap the example values for your own.
do these include security headers
Several, including Content-Security-Policy, Strict-Transport-Security, and a Set-Cookie with HttpOnly, Secure, and SameSite flags — useful references when hardening a response.
can i use these in production
Treat them as examples. The formats are correct, but values like tokens, origins, and policies must be replaced with ones that match your own application and security needs.
