Remarques

Si un client inclut les données du corps dans une demande, il déclare le type MIME Multipurpose Internet Mail Extensions () des données relatives au corps dans le Content-Type en-tête.If a client includes body data in a request, it declares the Multipurpose Internet Mail Extensions (MIME) type of the body data in the Content-Type header. Par exemple, le type MIME par défaut des données retournées à partir d’un formulaire Web en utilisant le POST méthode est application/x-www-form-urlencoded.For example, the default MIME type of data returned from a Web form using the POST method is application/x-www-form-urlencoded.

Le ContentType a la valeur null lorsqu’il existe aucune Content-Type en-tête dans la demande.The ContentType is null when there is no Content-Type header in the request.
