| 摘要 |
The invention enables a specification of a customized flow of pages for an interactive web application. Execution of page flows is differentiated from other aspects of execution. Instead of implementing continuations by using an entire procedure call stack, a separate, relatively small page flow stack is used to save state information relating to page flow. Additional resource economies may be achieved by analyzing a page flow processing program. In one embodiment, the invention is employed for expressing page flows associated with the checkout phase of an online store web application. An online store operator may define various kinds of common page flows that may then be provided to third-party merchants for use in customizing online store sites.
