Atributos de configuración CORS

Esta traducción está incompleta. Por favor, ayuda a traducir este artículo del inglés.

En HTML5, algunos elementos HTML que dan soporte para CORS, tales como <img><video>, tienen un atributo crossorigin  (propiedad crossOrigin), que les permite configurar las peticiones CORS de los datos que se cargan. Estos atributos están enumerados, y tienen los siguientes valores posibles:

Keyword Description
anonymous CORS requests for this element will not have the credentials flag set.
use-credentials CORS requests for this element will have the credentials flag set; this means the request will provide credentials.

By default (that is, when the attribute is not specified), CORS is not used at all. The "anonymous" keyword means that there will be no exchange of user credentials via cookies, client-side SSL certificates or HTTP authentication as described in the Terminology section of the CORS specification.

An invalid keyword and an empty string will be handled as the anonymous keyword.
