Answer 1

I think you need to place javascript timer on your page which will do ajax for example: "/Messages/GetLastUnreadMessage".

Answer 2

You'll need to have a bit of javascript that makes an AJAX call back to your site from the client page on a regular basis that checks to see if there are new messages, and displays them if there are.

There's no way for your web server to 'notify' an already rendered client page in the other direction (providing I understand your requirement correctly).

Answer 3

You probably need some javascript on your page that polls the server at a certain interval to check if there is something to show to the user.
