Establishing a link between numerous web browsers solely through client-side technology

After creating a compact AJAX-powered chat application, I wonder if it is feasible to handle all the communication client-side. Can individual pages recognize each other and share real-time updates without involving the server? Is there a way to achieve this using only Javascript?

I would greatly appreciate your insights on this intriguing topic!

Answer №1

Because of the same-origin policy, it is restricted for your JavaScript code to communicate with arbitrary third-party servers (and by extension, other users).

This restriction plays a crucial role in upholding JavaScript's security measures.

The solution lies in either going through the server or resorting to Flash (which has methods allowing for relaxation of such security constraints on the server-side).
