AJAX: Het web zonder wachten

 Asynchronous Javascript And Xml of kortweg AJAX is op het net een nieuwe hype aan het worden. Het grote voordeel van AJAX voor interactieve webapplicaties, is dat het deze meteen bijwerkt na input van de bezoeker, terwijl bij traditionele webapplicaties elke request naar de server wordt gestuurd en de gebruiker op een antwoord moet wachten.

Deze engine die de technologiën DHTML, CSS, XML, DOM en het object XMLHTTPRequest combineert staat standaard in ver elke recente browser (IE vanaf versie 5.0, Firefox, Mozilla) en zorgt ervoor dat er op de achtergrond communicatie met de server(s) mogelijk is.>

Tenslotte de voor- en nadelen tov de traditionele techniek

Voordelen:

  • Gebaseerd op open standaarden
  • Asynchroon: enkel wijzigingen worden van/naar de server gestuurd
  • De server heeft minder trafiek te verwerken

Nadelen

  • Trucs en hacks nodig voor compatibiliteit
  • Ontwikkeltoos nog niet volwassen
  • Moeilijk in zoekmachines op te nemen
