Abstract
Abstract A Web agency is interposed between a Web client and a Web server to transform the requests from the Web client prior to sending the requests on to the Web server, to transform the document returned from the Web server prior to sending the document on to the Web client, and to store state information about the user of various Web clients connected to the Web agency. The Web agency can be transparent to, and independent of, the Web client and the Web server. The Web agency might be used as a peripheral agency, a personal service agency or a document server. One such Web agency is a printer server which transparently renders documents. For hypertext documents, the rendering process includes generating machine-readable link references.
