API. XMLHttpRequest is a JavaScript Object used to execute asynchronous HTTP requests. Philip McCarthy describes a sequence diagram in his article (see figure 1). This diagram is helpful for understanding how XMLHttpRequest objects support Ajax design (see references, to obtain the link pointing to the full text ).
