There are two mechanisms used when determining if a web resource is pingback enabled; the presence of an HTML/XHTML <link> element with a rel attribute value of pingback or an HTTP header named X-Pingback. A web resource is considered pingback enabled if it utilizes either or both of these mechanisms. To conform to the Pingback 1.0 specification, the following information should apply to a pingback enabled resource: Pingback enabled resources that utilize the link mechanism will contain a <link rel="pingback" href="{Absolute URI of the pingback XML-RPC server}" /> element. Pingback enabled resources that utilize the HTTP header mechanism will contain an HTTP header named X-Pingback whose value is the absolute URI of the pingback XML-RPC server. This method is optimized to determine pingback enablement by examining the HTTP headers before attempting to parse the response data for an pingback XML-RPC server link.

The to validate. A that provides the proper set of credentials to the web resource when required. If is null, request is made using the default application credentials. true if the is pingback enabled, otherwise false. There are two mechanisms used when determining if a web resource is pingback enabled; the presence of an HTML/XHTML <link> element with a rel attribute value of pingback or an HTTP header named X-Pingback. A web resource is considered pingback enabled if it utilizes either or both of these mechanisms. To conform to the Pingback 1.0 specification, the following information should apply to a pingback enabled resource: Pingback enabled resources that utilize the link mechanism will contain a <link rel="pingback" href="{Absolute URI of the pingback XML-RPC server}" /> element. Pingback enabled resources that utilize the HTTP header mechanism will contain an HTTP header named X-Pingback whose value is the absolute URI of the pingback XML-RPC server.
