HTTP Header Checker
Fetch a limited public HTTPS response and show the status and headers, under strict request controls.
Your result
Type an address and press Look up to see its response headers.
How to use it
- Type an https address with a public hostname.
- Press Look up.
- Read the status. Redirects stay not followed.
Examples
- Public pagehttps://smart.example/ status: 200 content-type: text/html strict-transport-security: (none) location: (none) set-cookie: (none) redirects: not followed
- Cookie presenthttps://smart.example/cookie status: 301 content-type: (none) strict-transport-security: (none) location: https://smart.example/new set-cookie: present redirects: not followed
- Missing pagehttps://smart.example/missing status: 404 content-type: text/plain strict-transport-security: (none) location: (none) set-cookie: (none) redirects: not followed
Tool details and privacy
Type one https address. This site requests that public address once, without following redirects, and shows the status and a few headers. A Set-Cookie value is not shown.
The status and a short header list show what the public response said. The page does not follow the next address and does not print a cookie.
Options
- Only https on port 443. An IP address is refused.
- The response is not cached, because the address is arbitrary.
- A private or reserved address is not requested.
Limits
- The download is capped and the request times out.
- Set-Cookie is reported as present or (none).
- An http address is refused.
Privacy
What you type is sent to this site so it can ask a public service or DNS. It is not stored in the tool analytics. A failed lookup is an error, not a made-up result.
Questions
Are redirects followed?
No.
Is the Set-Cookie value shown?
No. The line says present or (none).
Can I check an IP address or an http address?
No.
Is a private address requested?
No. The lookup stops before the request.
