pushing data from the server (disconneted aspnet server approach)

[radiax]

I have been trying to find a way for a server to push data to a client (aka
disconnected server approach) but iam still stuck. This is the scenario: a
client is using a webclient to communicate with the aspnet server. Is there
a way for a server to send data to a client without a client requesting it??
I know it can be done using sockets but does aspnet provides a way? can a
webservice do it?? iam trying to find another solution besides sockets and
my preference is using aspnet if possible since i want to use subdomains
rahter than ipaddress.
thanks all

A simple way which isn't exactly what you might want would be to use AJAX.
The client would still poll for the data, but it could do so on a timer
running in the background.

My AJAX.NET article has an example that does just this...it looks like it's
a push even though it's really pull...

Thank you, Iam going to try using AJAX but I still doubt if it will satisfy
my demands. More likely I may end up abandon aspnet and go straight to the
bones, using sockets. I try to avoid sockets with the intentions of using
subdomains in aspnet under the 2 reasons: 1- I use a shared single ip
address and 2- i want to use port 80.
