Abstract: Initially, a client requests a specific document and provides the preferences, including readability level preferences of the document, locale preferences, content filtering instructions preferences, governmental regulations preferences, natural language preferences, and document syntactic format preferences. The transcoding proxy requests and receives the document from the origin server, with the document having origin semantic characteristics. The document from the origin server has an origin readability level and origin locale, is conformant with origin content filtering instructions and origin governmental regulations, and is in origin natural language and in origin document syntactic format. Using the client semantics preferences, the transcoding proxy revises the document in a sequential or parallel fashion. The origin semantics characteristics of the document are, thus, revised to the semantic preferences specified by the client.

Abstract: A method of outputting a document on a rendering engine in a client in a computer network. The document comprises a markup language data stream having a plurality of references to external resources required by the document. In operation, the document is first retrieved to the client. As the document is received, the rendering engine parses the markup language data stream for a list of external resources. If the list of external resources is present in the markup language data stream, the engine selectively prefetches at least one external resource as the document is output by the rendering engine.
