Delayed load regions can improve the server processing time of a page.
It works by ignoring the contents of this tag in the initial page load.
The contents are then loaded via a second AJAX request after everything else.
The main use case is to make secure server-side API requests without affecting performance.
For instance: loading data from an external feed, then presenting it in a repeater.
The AJAX request and this library's code makes the total download size of your page larger, so use of this control is recommended only to defer server processing time.
The content to load later.
(Required) Give this control a unique id. Can be accessed in the client DOM (eg, document.getElementById('myid') or in the server DOM using [? $myid ?] or [? $('myid') ?]).
