Direct to a specific page

Hello, I would like to make a link point directly to a page inside of my site for my affiliates, how can I do that?

Now:
my site = http://www.mypage.com
affiliate link = http://www.mypage.com?ref=name-83

What I want:
my site = http://www.mypage.com
affiliate link = http://www.mypage.com/product1?ref=name-83

Thanks
