<iframe src="the_page_you_want.html" width="400" height="400"></iframe>
If you put this in a table or use css this works nice and if you want a link to open in it you would give the iframe a name="name"so it would look like this: <iframe name="name" src="the_page_you_want.html" width="400" height="400"></iframe>
Then you can open a link in the iframe like this <a href="new_page.html" target="name">new page</a>
I think you might be talking about copyright infringement, and in that case don't do it; Leafypiggy and x10 will shun you; andNope. Iframes are the devil's work. Nope.
the problems are the extra strain on the server and you can't use a server side include as a target like you can with an iframe.<!--#include src="your_page.html"---> and change your page to an .shtml
