Abstract

A system having a distributed web site is described. The web site is distributed between a client, a server and a web server. The client stores a set of predefined applications that correspond to a part of the web site. The applications are formatted according to a first markup language. From the set of predefined applications, the client can generate queries. The server receives the queries and generates new, related queries. The new queries correspond to a second query protocol. The second query protocol is used by the web server. The web server generates responses to the new queries and sends these responses to the server. The responses are formatted according to a second markup language. These responses correspond to the second portion of the web site. The server then converts the responses into new responses that the client can use.
