    about AJAX

    I have some questions:

    1) What was used to write the AJAX engine, the javascript?

    2) Is the AJAX engine downloaded from the server to the client (Browser)?

    I mean, is the following process correct?

    --At first the client/browser does not contain the AJAX engine;
    --Then the browser makes a request to the server;
    --The server send back the AJAX engine or the AJAX engine is download to the client;
    --The client then can make the AJAX call

    3) If the 2) is correct, then how is the AJAX engine downloaded?

    What could be the statement(s) that can trigger the downloading of the AJAX engine?


    Thanks

    AJAX ain't no engine!

    AJAX - Asynchronous Javascript and XML - Is just a new, dynamic way of sending requests to the server. It does not have its own engine, it runs off of javascript and a little ActiveX thing for IE, which does not behave with AJAX the same way that every other modern browser does...

    I wrote something similiar to another one of your posts on another forum, writing it here for anyone that reads.

    The Ajax engine was a term coined when Ajax first started that was used to describe the native or ActiveX XMLHttpRequest object. There is nothing to be downloaded sice it is built into the browser and all it does is make an http request. Nothing fancy going on.
