first have a look at our offsite links's AJAX-section ...

basicly it is a combination of known techniques to avoid page-reloads by using the XMLHttpRequest-Object that first was introduced by Microsoft as an ActiveX-Object ... newer browsers have a build-in XMLHttpRequest-Object that you can use. It allows you to execute a request in the background and use JavaScript to process the request's response and update specific parts of your page instead of reloading the entire page. with that you may create a more 'desktop application'-like website that could! have a better 'user experience' in terms of usability and/or responsiveness ... that's a kind of the 'big picture' of AJAX = Asynchronous JavaScript and XML ... where the XML and asynchronous are a little bit optional ... instead of XML the most preferred return-structure is JSON and a request could even made synchronous ... with some drawbacks ... so the XML is more optional as the async is ;)

in case you have more specific questions after reading through some articles, then come back and ask them ...

kind regards
