Exactly, Mike.
As I replied to Mike, what does this have to do with optimistic vs
pessimistic locking?
while web browsers may be stateless, does if matter when
one maintains state on the server and can tell if the browser is active
(both quite do-able?)
By definition, if your client is stateless, it is not possible for the
server to "know" if it is connected. If you create a system in which
the server is "aware" of the client being connected, then it is no
longer a stateless client, and you must now deal with the issue of
scalability due to concurrency. If you have a popular, public
website, this could be a real problem, but maybe your website is not
public nor popular. Perhaps it is an internal/company website. In
that case, your stateful (?) client solution may scale perfectly
fine.
I don't know why it is so difficult for people to look beyond their
specific development situation when considering the merit, or lack
thereof, of a suggested design approach.
