Hi guys.

I wana to know some thing here.
I have a site where there are a lot of pages and directories.

For example site name is www.site.com (this is the index page).
Now if the user go to another pages for example click on the about link. How can i do this that the
site name appear in address bar remain the same as www.site.com not www.site.com/about.php
and so on for all pages.

Thanks in advance.
