ASP.NET 2.0 has a wealth of new features to offer: everything from an improved security model to new controls. However, the most interesting new feature for many developers may not ASP.NET's improved widgets for developing applications, but the improved control that custom browser setups can provide. Instead of waiting for Microsoft to add support for a particular browser, you can add this functionality yourself using a specially formatted .BROWSER file. The old method of detecting a browser relies on BrowserCap.DLL. This DLL detects the user agent entry, provided by the client machine, by using a simple wildcard match.
