Get HTTP Header & Security Header Checker
See every response header a URL returns, follow its redirects to the final address, and check the six key security headers.
HEAD asks for headers only (falls back to GET if the server rejects it). Some servers send different headers for GET.
Try example:

Frequently Asked Questions
HTTP response headers are metadata key-value pairs sent by a web server to the client's browser before delivering the page content. They communicate status codes, caching instructions, content types, and security policies.
