This demo demonstrates creating a window and loading the content of the window from a URL using the southprojects AJAX Transport.
The URL contains HTML to define the southprojects DHTML menu, combining the window and the menu in one web page.
There is a difference between opening content in simple window and iframe based window.
The HTML in the simple window behaves the same as any other HTML on the page. Clicking on a a link will reload the whole page and you can not include headers in the loaded page
HTML in the iframe window behaves like a separate page. Clicking on a link will load the page in the window. The page needs to be a full HTML page with headers.
