HttpCapabilitiesBase is the base class from which the HttpBrowserCapabilities class is derived. HttpCapabilitiesBase offers a large number of read-only properties that provide type-safe access to a browser's capabilities dictionary. You can access the HttpBrowserCapabilities class through the Browser property that is exposed by the ASP.NET HttpRequest.Browser property.
The following example shows how to access information about the browser.
