Basically it is a way of sending data from client to server and a mechanism for pushing server data back to the browser.[1][2]

This server–client communication takes one of two forms:

  • Client polling: the client repeatedly queries (polls) the server and waits for an answer.
  • Server pushing: a connection between a server and client is kept open and the server sends data when available.

Reverse Ajax describes the implementation of either of these models, or a combination of both. The design pattern is also known as Ajax Push, Full Duplex Ajax and Streaming Ajax.

Examples

The following is a simple example. Imagine we have 2 clients and 1 server, and client1 wants to send the message "hello" to every other client.

With traditional Ajax (polling):

  • client1 sends the message "hello"
  • server receives the message "hello"
  • client2 polls the server
  • client2 receives the message "hello"
  • client1 polls the server
  • client1 receives the message "hello"

With reverse Ajax (pushing):

  • client1 sends the message "hello"
  • server receives the message "hello"
  • server sends the message "hello" to all clients

Less traffic is generated with Reverse Ajax and messages are transferred with less delay (low-latency).
