HTTP Request Headers

What Are HTTP Request Headers? HTTP request headers carry metadata from the client to the server, specifying details about the request. Common headers include `User-Agent`, `Authorization`, and `Accept`, which inform the server about client preferences, authentication credentials, and accepted formats.

Why They Matter: Request headers enable servers to provide personalized responses, enforce security rules, and ensure efficient communication between clients and servers.

This is the printer-friendly version. See the colour HTTP Request Headers flyer.
