Remarques

Le Accept en-tête est une chaîne de séparées par des espaces de noms de types MIME Multipurpose Internet Mail Extensions () (par exemple, image/jpeg), qui indiquent les types MIME que le client est prêt à accepter et traiter dans une réponse.The Accept header is a string of space-separated Multipurpose Internet Mail Extensions (MIME) type names (for example, image/jpeg), which indicate the MIME types that the client is prepared to accept and process in a response. Le */* entrée indique que le client accepte n’importe quel type MIME.The */* entry indicates that the client accepts any MIME type. Pour une description détaillée de la Accept en-tête, consultez la RFC 2616, disponible à l’adresse https://www.rfc-editor.org .For a detailed description of the Accept header, see RFC 2616, available at https://www.rfc-editor.org.
