New programming techniques allow of individual data exchange with the server:

• GoogleMail reports without reload when new messages have arrived.
• Writely, the online word processing programme, opens contact menus after right click.
• Google Maps zooms maps without resending the entire request to the server.
• The web is more and more turning into an application, offering look & feel of programmes locally installed on the PC.
• The secret is the new technology called Ajax.
• Ajax stands for “Asynchronous JavaScript and XML”.
• The combination of these two techniques allows the exchange of only specifically requested data between browser and server.
• Ajax provides for new contents on the website without having to completely reload it.
• The traditional web organisation in sites is taken over by new web applications as fast as desktop software.
• In addition, Ajax enables the mixing up of different web offers since data can derive from diverse sources.
