It looks like a session ID.
That thing is usually carried in URLS if the server side language cannot use a cookie.
The session is there to preserves information across all the pages.
It usually stores this id in a cookie, but if the browser/client don't store cookies, then the session is lost.
Thus, the session id is transferred by automatically adding the session id in the url, as a GET parameter.
What I see, going on your site, is that the first link I click have this information, meaning that the site put it if it don't find a cookie, and try to put this value in a cookie.
The second page I load, the id is gone, meaning that as the cookie is there, the site don't see the necessity to add the id in the url.
Therefore, this parameter you see is there because the crawler don't stores cookies, and it's a way of the web site to get around this limitation.
