You won't get functionality from this out of a web browser and simple HTML.
The best you can do is have the client send a request to the server every so
often to check for updates.
You can have the client refresh on a regular basis with a meta tag like
this:
<META HTTP-EQUIV="refresh" CONTENT="3">
That will cause the browser to refresh every 3 seconds.
Or you can do this programatically from client side code such as javascript
:
location.reload ();
You can use SmartNavigation to make these refreshes less annoying to the
user.

If you need richer communication you'll have to design it yourself using a
thick client and your own networking code.
For this kind of thing you can use Remoting and the TCPChannel class.

Hi all!
I need some help with asp.net!
Is there any way to make the client BROWSER (IE, NETSCAPE, OPERA etc) to
wait for messages from a http/https host (server) in an internet
environment?
The main idea is not to refresh the client page or a component at a moment
of time, but to make the server push some messages to client when changes
are made into database.... Refreshing the page every x seconds/minutes
makes traffic on the internet for nothing...
What is .NET Remoting?
Please post an example.
PS: A method I found is to use java applets with sockets connected to
server... But I only want to use ASP.NET with VB.NET.
