Explanation:
CDE
Has anyone an explantion for that?
I think it should be BDE. Server push is about server pushing data to client with out client explicitly making request to the server.
In case of Auction, News and Sport applications, the data gets refreshed on client UI in a timely manner.
WebChat is explicit request from Client to the server. It may not be Server Push.

Most web feeds, such as RSS are technically pulled by the client. With RSS, the user’s RSS reader polls the server periodically for new content; the server does not send information to the client unrequested.
