How to Add Clean Url for Custom Pages
 

Ok I created a custom vBulletin 4.x page, as you know you can set clean url as basic, medium or advance. My question is on my custom page that I created, for example I have a link
<a href='index.php?foo=1&moo=2&boo=3'>bla bla bla</a> if you click on it, it will direct you to index.php with all those ugly parameters. Is their any built in function in vBulletin that can clean those url and display the clean url just like all those other clean url that are on your other pages? I have checked searching all over the forum for such tutorial on how to code it and could not find it.
