Modeling Web Interactions

Abstract:
Programmers confront a minefield when they design interactive Web 
programs. Web interactions take place via Web browsers. With browsers, 
consumers can whimsically navigate among the various stages of a dialog 
and can thus confuse the most sophisticated corporate Web sites. In 
turn, Web services can fault in frustrating and inexplicable ways. The 
quickening transition from Web scripts to Web services lends these 
problems immediacy.
To address this programming problem, we develop a foundational model of 
Web interactions and use it to formally describe two classes of errors. 
The model suggests techniques for detecting both classes of errors. For 
one class we present an incrementally checked record type system, which 
effectively eliminates these errors. For the other class, we introduce 
a dynamic safety check, which catches the mistakes relative to 
programmers' simple annotations.
