I found the solution,
I gave a class to each url zone of the text, e.g:
<a href="http://hotmail.com" class='insideLink' rel=nofollow>http://hotmail.com</a> test blablablab...
and I add the following jquery command in my script
$('.insideLink').click(function(event){
event.stopImmediatePropagation();
});
