Remarques

L’en-tête Accept est une chaîne de noms de types MIME (Multipurpose Internet Mail Extensions) séparés par des espaces (par exemple, image/jpeg), qui indiquent les types MIME que le client est prêt à accepter et à 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. L’entrée de */* indique que le client accepte tout type MIME.The */* entry indicates that the client accepts any MIME type. Pour obtenir une description détaillée de l’en-tête de Accept, consultez 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.
