The wording of this idea troubles me a little.  Because most back-end Web
applications don't need to be synchronized with the user interface.  The
notable exception, of course is a 5250 program that is running through a
program like Jacada.  IBM's new Webfacing solution will also have this
synchronization requirement.

But most Web applications simply process the request coming from the
browser.  If the user requests the "edit" form, then backs up to the "add"
form, then presses <enter>, it's not like the back-end is expecting the
"edit" form.  The back-end will simply run through the "add" logic.
