What Is the XMLHttpRequest Object?

The XMLHttpRequest object is the heart of all asynchronous operations related to Ajax. It is the object responsible for providing the asynchronous behavior through which Ajax-style applications can interact.
XMLHTTP is a protocol that is designed to package data as XML and send it via the network to a specific destination, or endpoint. This information is typically processed in some way, and the result is returned to the caller. The XMLHttpRequest object is an object that is implemented by most modern browsers to facilitate this communication protocol.
