[Javascript] Iframe: load same URL using JS

When something is not working in a simple plain HTML, it is futile to

persist in trying to make it work through dhtml. 

 

p.s.:

Might be security restriction, but I doubt it. Because IFRAME is a

documentElement if I'm not wrong, and loading the same content

in both will exactly yield an infinity parallel mirror effect,...
