<script type="text/javascript">
alert(document.referrer);
</script>

If you control the original page, then you could put a source in the URL like this:

<a href="http://www.sample./check/?code=2&scr=http://foo./xxxx">Code2</a>

and you could parse that out of the URL in the 2nd page.

Or you can look at document.referrer in the 2nd page and see if it contains the value you want. See https://developer.mozilla/en/document.referrer for info about the referrer.
