How does ajax request actually work?

Sachin Singh

when we type url in browser , the browser follows the rules defined by Http and construct the Http message in an appropriate format like header and body , this is how request leaves the application and travels through the other network points.

In case of Ajax , how browser makes an asynchronous request? or is it directly handled by the Javascript engine embeded in browser, and he only construct and send the http message to the network without any help of other component of Browser , internally??

I think there is no difference between a ajax request and normal http request from browser's perspective,
the only difference is , the browser sets x-requested-with header to XmlHttpRequest , apart from this, both the requests are exactly the same.Among all browser components like interface, layout engine, rendering engine, JavaScript interpreter, UI backend, networking component and data persistence component, networking component is the one responsible for making a request , irrespective of a request from javascript or browser's UI.
