using RIFE we built several applications that use continuations to perform 'islands of functionality' (unit of work). One of those is publically available as Bamboo ( Tue, 18 Jan 2005 12:10:11 -0500 Tue, 18 Jan 2005 12:10:11 -0500 Tue, 18 Jan 2005 12:10:11 -0500 Jan 18, 2005 gbevin 0 Use continuations to develop complex Web applications http://www.theserverside.com/discussions/thread.tss?thread_id=30764 How Cocoon uses continuations is akin to an Ada rendezvous. Even though a UML activity diagram can show rendezvous, there's an inherent lack of modularity to continuations that make them ill-suited for automations such as reflection,...]]> Thu, 30 Dec 2004 22:54:17 -0500 Thu, 30 Dec 2004 22:54:17 -0500 Thu, 30 Dec 2004 22:54:17 -0500 Dec 30, 2004 Antonio Gallardo 0 Use continuations to develop complex Web applications http://www.theserverside.com/discussions/thread.tss?thread_id=30764 What if browser sends a page which is not a form and does not have continuation ID attached?

On the opposite, this is the perfect separation of concerns.
