   You can also use the new MooTools More URI syntax which also works with base-tags.

   window.addEvent('domready',function(){
       var baseHost = URI.base.get('host');
       $$('a[href^="http://"]').each(function(a){
           var uri = new URI(a);
           if(baseHost != uri.get('host')){
               var favicon = new URI('/favicon.ico', { base: uri });
               a.setStyle('background-image','url(' + favicon + ')').addClass('favicon');
           }
       });
   });

   Grat one, even better idea!!! I created something similar adding icon to for all external links using URI subclass http://mootools.net/docs/more/Native/URI

    window.addEvent('domready',function() {
           var host = window.location.host;
           var links = $$('a');
           links.each(function(elem,i){ 
               var myURI = new URI(elem.get('href'));
               var hostExtern = myURI.get('host');
                   if(hostExtern!=host) {
                     elem.addClass('web');
                   }
            })
   })

   Actually, since you’re not using the link URI for anything else you don’t have to create another object.

   Just use uri.set('value', '/favicon.ico'); Set value will take relative paths.

   Nice one David! Simple but very effective!

   Cool idea !

   As not all website are having a favicon, I added some stuff to check if the favicon is properly loaded.
   If not, the background-image should not be changed, and remains the default image I use to indicate external links.

   My inner code block looks like this:

   var favicon = href.replace(/^(http:\/\/[^\/]+).*$/, '$1') + '/favicon.ico',
        img = new Image();
   
   img.onload = function(){
       a.setStyle('background-image','url(' + favicon + ')');
   }
   img.src = favicon; //load it now.
