Trigger a jsp page refresh when some value in the server changes.
Ajax is an option, but refreshing the JSP at a particular interval will increase the load on the server. Since i am dealing with a system that handles large amount of data, optimizing with the best having the higher priority.
Any new Technology or design pattern that may help is greatly appreciated.
NB : I have seen the technologies that match my requirement in HTML 5. But i am looking for something that works with everything.
