Inspect response headers returned by a public HTTP or HTTPS URL without following redirects.
About HTTP Headers
Inspect response headers returned by a public HTTP or HTTPS URL without following redirects. cURL sends a header-only request to the public URL and returns the response headers without following redirects.
How to use HTTP Headers
Enter a public URL and run the check. ToolFlow makes a header-only request without following redirects and displays the response headers returned by the server.
When HTTP Headers is useful
- Investigate a public website during development, deployment or SEO review.
- Verify an HTTP, DNS or TLS detail before changing server configuration.
- Capture a point-in-time diagnostic result without installing a local command-line tool.
Practical tips
- Run diagnostics against a public URL you are authorized to test.
- A single request is a point-in-time measurement; network and server conditions can change between checks.
- For production decisions, confirm important findings with server logs or authoritative configuration data.
HTTP Headers FAQ
Does HTTP Headers change my original input?
No. ToolFlow works on a temporary upload or submitted value and returns a separate result. Your local original is not overwritten.
Can HTTP Headers access private or local network addresses?
No. ToolFlow is designed to reject localhost, local domains and private or reserved IP ranges before making a server-side request.
Privacy and file handling
This diagnostic sends a server-side request only to public addresses after private and reserved network ranges are rejected. The destination website may record ToolFlow's server request in its own logs. See the Adatvédelem for details.
