Hi everybody,

I'm developing an application using ASP.Net.

For first the idea: "My WebApp needs an cronometer to be shared by users and all users will se the same value in cronometer. When a user clicks on a button, the cronometer needs to be restarted and all users will need to see that!"

All right, now I'd like to know what's the best choose to improve more performace an make sure that all users will see the same value in cronometer ?

Need I use JSon (with jquery in client side), Timer with UpdatePanel of Ajax Extensions, pure Ajax (with JQuery) or any idea to suggested ? Any suggestion for how to shared a cronometer for all users in C# (put information in Cache or database) ?

Thanks all

Cheers
