Broadcast a change to all listeners?

[Bruce W...1]

Say I had an ASP.NET page that monitored the status of something. If
this status changed is there a way to cause an update on all browsers
that are viewing this page?

I know this isn't in keeping with a connectionless state. I suppose I
could make the page refresh once a minute, but this is not ideal. So
I'm thinking along the lines of UDP or something.

Does anyone know if this can be done with ASP.NET?

Thanks for your help.

the browser only supports polling, you can wrtite a activex or java applet
that uses some variant of IM. UPD will not work as it is not routed. the
applet will need to keep a continous connection, so your server will need to
be configured to handle it.
