How to make homepage always display controller/method in URL?

[eluser]toymachiner62[/eluser]
When you first go to my website, it is like

Code:

example.com

. Say you click on the about page, it is

Code:

example.com/site/method

, then if you click on the home link it takes you to

Code:

example.com/site/index

.

How can I make it so that when a user first goes to

Code:

example.com

, it will show

Code:

example.com/site/index

?
