Why Gaia Ajax?
The ASP.NET world needed a fast, lightfoot and intelligent library.
Gaia boosts your webapp development using C# or VB.NET and your existing ASP.NET knowledge. Gaia only sends what has changed back to the browser.
The result: a rich and responsive user experience.

Gaia Ajax: BrowserHistory

The BrowserHistory Control allows you to add states to your application by using the AddHistory function. When the user clicks back in the browser, the state info will be passed to the server in the Navigated event. This is an Ajax request where you can restore the state of your application based on this information.
