Since 2005, many programmers has used AJAX technologies for creating their websites. The core of these technologies is to update only that part of the page that does need changing. Nowadays, a website sending all its contents to a user at any request looks outdated. Professional web studios are most likely to give up using this method to create web applications soon.

When developing applications in the ASP.NET 2.0, we started applying AJAX in our projects. A great number of different libraries had been studied before we realised that a ready-made solution that would suit us completely could not be found. As a result, we started developing our own technology that would meet the following conditions:

- An application should work equally in any browser supporting the www.w3.org standards.
- The AJAX application development must not be fundamentally different from that of the ASP.NET standard application.
- The technology must work with any controls (both standard Visual Studio controls and controls from libraries of the third-party firms).
- Time you spend on changing existing ASP.NET projects must be far less than that you spend on rewriting them.
- A website must easily be indexed by search engines.
- User operation with the AJAX website must be the same as with any other site.

As a result, some other options were also added. For example, a programmer can flexibly control browser navigation buttons and cut off data resending to a server, which happens because of double-clicking the buttons. For more information on this technology, please visit the Help page. We, however, first recommend you to start with the Demo project where you can convert the ASP.NET standard application into the AJAX project.
