Web applications and client/server applications are totally different
animals. In client/server, you know you have a connection to a client
application that's presumably talking to a human. If he asks for a
multiple page display, you can be reasonable assured that he'll either
ask for them or for something else, in which case, cached data can be
flushed. In the web world, there is no connectivity to a client and
each page is an atomic operation. What the user might do or if we will
even hear about it is unknowable.
