This is how you do it. It´s called an iFrame. Sure, you can use other methods, but when you want to put a web page in a web page, this is the most handy and reliable method.
I find this useful when I want to put a web page in a web page. But not the whole page, just a part of the page. Like, I don´t want to use all of WordPress, but maybe I just want to put in a form, search box or any other cool WordPress widget into my well controlled site. This way, I can bring in just what I want, and put it positioned exactly where I want it to go.
So, when I want to put a web page in a web page, specifically, if I want to put A PART OF A WEB PAGE IN A WEB PAGE, I use this method.
