Interface-Parasite Gateways
Robert A. Barta, Manfred Hauswirth · 1995
Apart from challenging new possibilities in resource discovery and retrieval, WWW gives the opportunity to provide legacy applications with a new look and feel and to add functionality without having to change the software itself. We describe problems and possible solutions in the area of connecting legacy software based on terminal sessions to WWW, especially focusing on the problems that arise from adapting stateful interactive services to the stateless HTTP. As a case study we present a WWW gateway to a stateful legacy application (Austrian national academic OPAC) by encapsulating it within a CGI conformant gateway.
