  Hello,
 is there a possibility to include a website directly as a wiki page, so that clicking on
a link, that redirects you to an external (www) page, loads the website directly as a
"frame" in my xwiki instance. At the moment I am only able to create links that
load the external site in a new tab or page. 
Sure that's easy to do using $xwiki.getURLContent wrapped in a {{html}} macro.
See for ex:

Hope it helps,
