I know in the WApplication's session, I can use WApplication::instance()
to get the instance, But It's just one instance of one session, if I want
to push data to browser, I must to get all keep-alive instances, so I
think maybe the Wt framework store all instances that status is
keep-alive,
maybe It use a queue or something else. So if I can direct access this
structure or some function to get the structure, I can poll data to all
keep-alive instance which can be grabed itself update lock, then call the
instance's functions to modify widgets. So, do I can get this structure?
How?
