The World-Wide Web Gateway to Hyper-G: Using a Connectionless Protocol to Access Session-Oriented Services

Abstract

In this thesis, possibilities are studied how session-oriented services on the Internet can be made accessible to users of client programs that use a connectionless application-level protocol. The concepts and properties of two Hypermedia Information Systems, the World-Wide Web (WWW) and Hyper-G, are described and a comparison between these two systems is given. A gateway program was developed which is used as a protocol converter between the sessionoriented Hyper-G client-server protocol and the connectionless Hypertext Transfer Protocol (HTTP). A mechanism was implemented that allows to differentiate HTTP requests and to assign them to Hyper-G sessions. The gateway provides users of World-Wide Web client
