Daniel, ASP.NET does not directly provide a server push mechanism, but you can implement one yourself if you have a client that will be able to listen for incoming connections. Unfortunately, this is not widely supported by browsers so you would most likely have to write your own client or provide a thick client (ie dll) that will do the listening. A most frequently used alternative is a refresh header in your page that will trigger a frequent refresh, which combined with a smart server-side caching scheme for your page (check out the asp.net output cache for more info) can be a good alternative to a server push. Hope this helps,
