Background - problems with "normal" use of Ajax

Ajax is a technique used for updating web pages live ”on the fly” without using a full refresh of the page or the frame. The web page appears to be alive. Ajax is growing in popularity and has become widely used. Normal use of Ajax means that:

1. The web client asks a server for new information.
2. If the server has new information it will send it to the client.
3. The client receives the information and updates the page in the browser.
4. After a timeout (for example after 3 seconds) the web client again asks a server for new information, and so on...

There are some problems / disadvantages with normal use of Ajax:

• The client will ask for new information even if the server doesn’t have any new information. This will result in unnecessary use of bandwidth and of web server capacity, especially if there are a lot of concurrent clients.
• The information can never be shown in real real time. A delay is necessary. The delay is probably not acceptable if the client has to have instant information if the client for example is a financial trader or if he/she is betting.
