Hello everyone,
I don't know if it is possible at all.
I have to build a site that will work as a gateway/relay between its visitors/customers. Customer A should send message to Customer B via web form, and vice versa. An ordinary raw http should be used. The speed of communication is not of major concern, but it should be "something like" real-time, meaning, when there is a new message for customer B, site should inform it that it should reload current page or go to another.
Any idea or comment will be very useful. Thanks in advance.
