one HTML page within another?

For example I have a main page with a div ( or something of that kind ) within which I want a content page to app开发者_Python百科ear. What do you think would be the best way of doing this?

Thanks!

If you are using PHP, include('page2.php') is the best way to. if not, <iframe src="page2.html"></iframe> is good.
