HTTP Header Inspector / Checker

How to use HTTP Header Inspector / Checker

Enter a public HTTP/HTTPS URL on its default port. Inspect one response without following redirects. HEAD is used first; 405/501 triggers a GET stopped after headers. Review observed headers and informational header-presence indicators. A missing or present header is not a security grade. Server/browser responses can differ.

What does the result mean?

Reports describe observed responses or the structure of your supplied bytes/table. Results do not establish site security, validate packet checksums or prove ARP spoofing. Read the tool-specific assumptions and any incomplete-result warnings.
