Ensure proper cross-domain Analytics tracking

analytics-cross-domain.js

	// Add 'external' CSS class to all external links
	jQuery('a').filter( function() { 
		// Only take action when a link leads to a different domain than the one we're currently on, 
		// and that domain is in the list of internal sites
		return this.hostname != location.hostname && this.hostname in umw_internal_sites;
	} ).attr( 'analytics-cross-domain', 'yes' ).click( function() { 
		// If the link is supposed to open in a new window, let it do so
		if ( jQuery( this ).attr( 'target' ) ) {
			window.open( jQuery(this).attr('href'), jQuery( this ).attr( 'target' ) );
		// Otherwise, tell Analytics that this is a link to somewhere else on our site
		} else {
			_gaq.push(['_link', jQuery(this).attr('href'), true]); 
		}
		// Stop the link from actually doing its job, since the script above will handle that
		return false; 
	} );
