HttpCapabilitiesBase Class

Provides access to detailed information about the capabilities of the client's browser.

Namespace: System.Web.Configuration
Assembly: System.Web (in system.web.dll)

'Declaration
Public Class HttpCapabilitiesBase
	Implements IFilterResolutionService
'Usage
Dim instance As HttpCapabilitiesBase

public class HttpCapabilitiesBase implements IFilterResolutionService
public class HttpCapabilitiesBase implements IFilterResolutionService
Not applicable.

HttpCapabilitiesBase is the base class from which the HttpBrowserCapabilities class extends. 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, which derives from HttpCapabilitiesBase, through the Browser property exposed by the ASP.NET HttpRequest.Browser property.
