HTTP pipelining Technology--ajax request

1. Pipeline technology--the client can send multiple requests to the server, without having to wait for the last request to respond to the next request. Implementing parallel Send Requests

2.ajax--implementing asynchronous refresh of Web pages

Issue: When the user makes multiple AJAX requests, and displays the content in the same element of the page. If the last request time is too long, the subsequent request time is short,

Will cause the last requested data to be overwritten with the following content.

Ajax provides a function that ends the last request, making the last request complete before each request.

The code is as follows:

        /* Terminates last Request *        /if (currentajax! = null) {            currentajax.abort ();        }        Currentajax = $.ajax ()
