I assume you are using some kind of web-based control panel provided by your host. The method will depend on what control panel you are using. I suggest you consult the documentation.

I could explain how to do it with Apache configuration files, but I doubt you have access to those directly. What will happen in your case is that changes you specify in your control panel will edit those configuration files in a more user-friendly fashion :)
