PingBackClient
Send synchronized pingback requests, to ensure pingback requests are processed at a specific time by the server.
This can be useful if you want multiple wordpress servers to process a pingback request at exactly one moment..
Example
This example will ask 'the-wordpress.fr' to process N http requests to the url: 'https://the-target.com'
// build configuration object for synchronized requests; // nb of requests to make; ;
