How to Inspect SSL, Headers and Redirects

Check certificate validity, HTTP response headers, and redirects as a connected website diagnostic workflow.

Three layers of an HTTPS request

A certificate check examines the TLS identity and validity period. An HTTP header check shows the response metadata sent after a connection succeeds. A redirect check reveals whether the requested URL sends the client elsewhere. Looking at all three helps distinguish certificate, application, and routing problems.

Check a site methodically

  1. Enter the hostname in the SSL checker and review validity dates, issuer, subject alternative names, chain status, and protocol.
  2. Inspect the final page headers for caching, content type, security policies, and server behavior.
  3. Trace both the expected canonical URL and common alternate URL to find extra hops or unexpected destinations.

Important result details

A valid certificate must be within its date range, chain to a trusted authority, and cover the requested hostname. SAN entries list covered names. Redirect status codes have different permanence and method-handling semantics. Headers such as Content-Type, Cache-Control, Content-Security-Policy, and Strict-Transport-Security influence browser behavior but must be evaluated in context.

Limitations

Results reflect what the KitBeam server can reach and may differ from a browser behind another network. A clean certificate and header report does not prove that application code is secure. Use authorized security review and application logs for deeper assurance.
