HTTP headers & redirects

Trace redirect chains with cache-disabled HEAD requests.

Uses HEAD requests with cache disabled; falls back to GET when HEAD is not supported.

All requests are sent from Germany (DE). Results may differ from your location if the target site applies geo-blocking.

About this tool

Generate and inspect HTTP headers online to debug API clients, bots, and browser-like requests in seconds. This free HTTP headers tool is useful when you need clean request templates for `curl`, Postman, or backend test scripts.

You can quickly compare user-agent presets and verify standard fields before shipping integrations. Teams often use this utility to reduce avoidable 4xx errors caused by malformed or missing headers.
