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.
