Link to a function like the following. It makes a GET request to the server
and opens a new window to the url. The link_to also follows.

<%= link_to_function truncate(article.title, 60),
"clickThru('#{article.url}','#{article[:id]}', 'click')",
:title => article.feed.title, :href => article[:id] %>

function clickThru(url, id, verb) {
new Ajax.Request('/articles/'+id+'/'+verb,
{asynchronous:true, evalScripts:true, method:'get'});
window.open(url);
}
