How do I make afflink.com/ref?bfja to afflink.com in address bar?

Is there any plugin that masks these affiliates codes and make them seem a single domain
in the address bar? I hope you understood me. It is not a link shrinker That I want. But
when hovering over the link the displayed link in the address bar should not have the
remainings of the link. Only the domain. I don't know if there is any such plugin but I saw
such a site.

 

Hey boy, show me the demo you've seen

 

Not exactly this http://www.hostmiles.com/ but a review of hosting website with tabs. Couldn't get it.

You know what? it feels as if the guy is not getting commissions because his links are something like "hostgator.com" in the address bar. But when you click on it, it shows up the real address. I think this is beneficial for affiliates.

 

I think they had used Apache via Htaccess

 

You have to use mod_rewrite in .htaccess to rewrite your URL's according to your specifications.

 

Any specific guide pls? or some WP plugin?
