Hi all

I want to develop a web app that has data originating from 3 sources, the sources are:

1) Database
2) Web service
3) Web-server

When any of the data changes on any of these 3 sources I want it to be reflected in in my thin client. Is there a way the client can be updated automatically or will it require me to poll my server for changes which in-turn is also polling the three sources??

Any help appreciated.

Kind regards

Deano
