Server contacting browser...technical thread...
Is there any way that the server is able to send an unsolicted message to a specific client?
For example, I am working on this dating site, and when I make changes in the admin panel, the test browser almost immediatly reboots and asks for my login again - this is normal action.
There are only 2 ways I can think of that this can happen:
1) The browser is contacting the main website every second to know if anything has changed.
2) The server, is somehow able to send a message to the browser...
I understand how to do method 1. The browser pings the website for some sort of session or update data or whatever.
But! Is method 2 even possible? Is there any way that the server is able to send an unsolicted message to a specific client?
I would never make a wesite "ping the server every second to find updates", since with 10,000 online visitors, that would be a huge load. So if there is some way to do method 2 that would be awesome.
Does anyone know if this is possible? Ideas?
