ASP.NET server notifications

[sundeep]

I am working on a ticker kind of a application using
asp.net. The issue is that we are not allowed to install
anything on the client. All what i can do is to show a
aspx page to the clients and auto refresh for the latest
data after some time.. just being curious if any other
option to send notification from server through HTTP?

It sounds like you're doing all you can do with the limitations that are
imposed on you.
No notifications can be sent from the server without it being a response to
a request from the browser.
That's just how HTTP works. If you want to use a more complex protocol
you'd need to install something on the client.
