Content negotiation: ask for what you can handle

HTTP content negotiation allows clients to tell servers what formats, languages, and encodings they support. The server selects the best available representation and responds accordingly.

This enables one URL to serve different content to different clients: English HTML to a US browser, French HTML to a French user, JSON to an API client — all at the same path.
