? AJAX library/toolkit/frameset to use ?

[Valentin L]

I'm new to AJAX ..

In my IIS5 web apps I'm using the old VBScript in .asp pages.

I've tested an AJAX banner rotator and is OK.

Now I'm looking "the" library that will spare me to "re-invent the AJAX
wheel"

I know how to use of the Browser's XMLHttpRequest and the
client-server-client mechanism.

"My AJAX" must be able to:

1. at the beginning, when the user's browser gets the first page, the FIRST
AJAX component

must be very little (in KB). No more than 1-2KB.

This "the first AJAX javascript code" loaded, should be just a preloader for
the next JScripts will come according to the user's actions ; For example if
the user will hit a Slideshow button then the preloader should ask from the
server some Jscripts for image effects (beside the asked pictures).

I don't want to download from the beginning the entire library! Only what is
needed.

2. among the "objects downloaded when needed" library, I would like to exist
a kind of TinyMCE - HTML TEXTAREA WYSIWYG editor ; and maybe many many
widgets as possible J

3. To let me compose on the server-side the html code that will be sent and
showed on that <div id="drop-it-here">

Who's the winner?
