Deze sessie was geranked als ‘Advanced’, maar had beter ‘Introductory’ kunnen zijn. Functies die we in web technologie gebruiken zijn veelal het afhankelen van de user request, het opslaan van een bepaalde state, het navigeren tussen verschillende pagina’s en dynamisch genereren van content. Kijkend naar de mogelijkheden die er zijn voor de webtier dan kun je ze ruwweg verdelen in Foundation technologies (servlet, portlet, JSTL, JSP) en Framework technologies (Struts, JavaServer Faces). In de rest van de sessie worden deze technologieen verder behandeld.
