What is an HTTP Headers Inspector?

HTTP Headers are key-value pairs exchanged between a client and a server during an HTTP Request/Response cycle.

Headers carry meta-information about the data being transmitted, such as content type, caching policies, authentication tokens, and server security settings (like CORS and Strict-Transport-Security).

This tool proxies your request to the target URL and renders cleanly everything the remote web server sends back before the actual HTML/JSON body is parsed.

1How to Use

  • 1. Paste a complete URL (e.g. `https://example.com`).
  • 2. The tool performs a GET request.
  • 3. Inspect the returned HTTP Status Code and exactly how the server dictates the payload should be processed.
