Website HTTP Headers Inspector — frequently asked questions

What are HTTP response headers?

HTTP response headers are metadata key-value pairs returned by a web server alongside requested content. They describe the payload format, caching directives, server software, compression algorithm, and security configurations.

Which headers are most important to inspect?

Crucial headers include Status code, Cache-Control, Server, X-Powered-By, Content-Encoding (gzip, br), and CF-Ray / CDN caching headers.

Can I inspect raw headers copied from curl or browser DevTools?

Yes. Switch to the Paste mode tab and paste raw header lines. The parser parses them directly inside your browser without sending any text to external servers.

How does this tool handle HTTP redirects?

When fetching a URL, the tool reports the initial response headers received from the primary target as well as any final redirection targets.

Does Sada Files keep a history of URLs or response headers?

No. URL fetches are performed strictly in memory and discarded immediately upon transmitting the response back to your client. No URLs, domain names, or header values are logged.
