History and url

Is it possible to not show the queryString the History object appends to the URL? For example, at http://extjs.com/deploy/dev/examples...y/history.html , not have it append #tab1:subtab1 automatically at page load or tabChange

Thanks

From looking at the source code, this looks like the only way of providing the history feature. That is, in order to get added as an item in the browser's history, the browser needs to see a new url, so the history class updates the url.
