I will demonstrate the problem on a real example so the situation:

  1. there is a website (eg: real example: http://www.news.com.au/breaking-news)
  2. From the website I want to parse data "last breaking news". This should be a service (based on php, c # aspx ...) do that is by our side written off. The data are parsed and prepared in XML or similar.
  3. There are a number of clients (desktop variant, mobile ...), when the news with a new PUSH (like an exchange server does that) should be notified.

I do not know exactly how to do the connection / synchronization between 2) and 3).

One idea would be sent by a client in an interval and then requests for the service needs to make a PUSH. Or is there some other variant to solve this? Maybe so that the client is waiting and the only large part of the service intervals made ​​without the requests?

Are there any specific approaches, ideas, proposals?

Thanks in advance, best regards.

  1. The client (i.e. Android app) is quering the server periodically, sending a timestamp value. The server compares the timestamp with its data and replies only with relevant (newest) data.
  2. Push notifications: on Android you can use C2DM. How to do it in PHP? See: C2DM implementation PHP code
