HTTP Headers Parser FAQ

What is a headers parser for?

It converts HTTP header blocks into JSON so cache, CORS, redirects, cookies, content-type, and security headers are easier to review.

Can I paste headers copied from curl?

Yes. Paste lines in Name: value format. Lines without a colon are ignored.

Does it validate CORS or CSP policy?

No. It structures headers for reading; final policy interpretation stays with you.

How are repeated headers handled?

The output keeps the original order and also groups repeated values by normalized header name.

Are headers sent to a backend?

No. Parsing runs locally in your browser.
