Abstract

L'invention concerne un procédé de chargement de ressources de pages web, comportant les étapes consistant à: recevoir des informations de demande envoyées par un client, les informations de demande comportant une adresse de page web correspondant à une ressource d'origine de page web et un identifiant d'origine correspondant à la ressource d'origine de page web; déterminer un identifiant d'une version la plus récente correspondant à l'adresse de page web; lorsque l'identifiant d'origine est différent de l'identifiant de la version la plus récente, calculer des données d'écart entre la ressource d'origine de page web correspondant à l'identifiant d'origine et une nouvelle ressource de page web correspondant à l'identifiant de la version la plus récente; et envoyer les données d'écart au client, les données d'écart et la ressource d'origine de page web étant utilisées pour générer la nouvelle ressource de page web pour le client selon une règle prédéfinie. L'invention concerne également un dispositif de chargement de ressources de pages web. En comparaison de l'état antérieur de la technique, le procédé et le dispositif de chargement de ressources de pages web décrits dans les modes de réalisation de la présente invention peuvent non seulement raccourcir le temps de chargement mais peuvent également économiser du trafic, car seules les données d'écart de la partie mise à jour sont chargées lorsqu'une ressource de page web à laquelle le client demande à accéder est mise à jour.
