Sending event from Server To client
I would like to know how to implement situation when the Web server need to send some event to the client browser because of some changes in the DB.
My question are:
1.How could I get the notification of this event from the client if the client itself isn't asking the server ??
2.Is the only way to solve this problem is to poll the server at intervals ??
3.Is it recommended in that case to use Win Forms because Web Forms can't handle this scenario ??
