HTTP Headers Checker
Inspect response status and headers for one public HTTP or HTTPS URL. This checker does not proxy response bodies or scan for vulnerabilities.
Results
Privacy and scope
The URL is sent only when you press Check headers. Learnova does not save URL history and the API response uses no-store caching. Redirects are followed manually and each redirect target is revalidated.
Security-header badges are informational only. Missing or present headers alone do not prove a site is secure or vulnerable. TLS certificate checking and port scanning are outside this tool.

About HTTP Headers Checker
Fetch a public HTTP or HTTPS target safely and inspect its response headers without returning the body.
How to use it
Enter the requested value, review it for accuracy, then run the tool. Read the labeled result fields before copying or using them in another workflow.
Understanding the result
The result presents the values returned or calculated for this specific request. Labels and status messages distinguish successful data, empty results, validation problems, and network errors.
Limitations and privacy
Private, local, reserved targets and unsafe redirects are blocked; the result is not a security certification. This check sends only the target needed for the requested lookup to the Learnova Network Tools service; no lookup history is intentionally stored by this tool.
