Content Negotiation
The mechanism by which a client and server agree on the best representation of a resource. The client sends Accept, Accept-Language, Accept-Encoding, and Accept-Charset headers to express preferences. The server responds with the most appropriate representation or returns 406 Not Acceptable if no suitable representation exists.
