HTTP Headers

Network

Fetch a URL, follow the redirect chain, and inspect every response header — with the security headers (HSTS, CSP, X-Frame-Options…) called out.

Use this from the command line

curl -s https://ipcow.com/api/tools/http-headers \
  -H 'content-type: application/json' \
  -d '{"url":"https://example.com"}'
