Cross-domain embedding for Vaadin applications

Abstract

Although the design goals of the browser were originally not at running applications or at displaying a number of small widgets on a single web page, today many web pages considerably benefit from being able to host small embedded applications as components. While the web is full such applications, they cannot be easily reused because of the same origin policy restrictions that were introduced to protect web content from potentially malicious use. In this paper, we describe a generic design for cross domain embedding of web applications in a fashion that enables loading of applications from different domains as well as communication between the client and server. As the proof-of-concept implementation environment, we use web development framework Vaadin, a Google Web Toolkit based system that uses Java for application development. © 2012 Springer-Verlag.
