Hi,
I am developing an app where customer post request via a website, the
request, upon receipt by the office, must the be pushed to respective mobile
PDAs.n The requests are sort of order pickup.

My initial design is based on polling, so my mobile users PDA will poll the
server every 2 minutes. Is there a better way to push the order notification
instead?

Any advice will be appreciated, or perhaps point me in the right direction.

Thanks
 
Hello Chris,

Look at SQL Cache Invalidation http://quickstarts.asp.net/QuickStartv20/aspnet/doc/caching/SQLInvalidation.aspx

Hi,
Thanks for the reply. My mobile users (with commercial PDAs) have a forms
application installed and uses a webservice to perform pooling. I am looking
for a way to push the updates instead of them having to poll.

Thanks
 
Your alternative would be to create a socket server on each client, and have
your web server connect to that and pass updates as a client to each server.
You'll not be likely to gain much over doing a poll to the webserver.
