While it is true that your site will show up as the referrer for most (but not all referrals), the best way to ensure your referrals show up and are properly credited, as long as the target site is using some type of tracking, is for the target site to create for you either a special entry URL: www.thatsite.com/referrals/frommysite.html; or that the target site use the commonly found query parameters scheme to identify you as the referring site: www.thatsite.com?ref=www.mysite.com
Using either of those later methods will ensure that your site is clearly identified when the browser hits your site. Counting on the httpd header for referrer information can be risky as the referrring site is not always included, and can be blocked by simplistic firewall settings.
