What is HTTP Headers Parser?

An HTTP headers parser breaks a raw request or response header block into readable name-and-value pairs. It helps debug caching, authentication, redirects, CORS, and content negotiation.

How to use this tool

Paste the complete header block, parse it, and inspect each header alongside its value. Compare it with the expected request or response behavior.

Useful notes

Header names are case-insensitive, but values may not be. Avoid sharing authorization, cookie, or API-key headers in public logs.
