Use of document.load forbidden on Documents that come from other Windows. Only the Window in which a Document was created is allowed to call .load on that Document. Preferably, use XMLHttpRequest instead.
L'uso de document.load ye vedau en documentos que promanan d'atras Finestras. Nomás a Finestra en a qual o documento s'ha creyau puede clamar a .load en ixe Documento. Millor faiga servir en cuenta XMLHttpRequest
