'''Push''', or '''server push''', describes a style of [[Internet]]-based communication where the request for a given transaction is initiated by the publisher or central server.

It is contrasted with pull/get, where the request for the transmission of information is initiated by the receiver or client.

== Description ==

Push services are often based on information preferences expressed in advance. This is called a publish/subscribe model. A client "subscribes" to various information "channels" provided by a server; whenever new content is available on one of those channels, the server pushes that information out to the client.

Push is sometimes emulated with a polling technique, particularly under circumstances where a real push is not possible, such as sites with security policies that require rejection of incoming HTTP/S requests.
