How to set querystring with Javascript
<p>Is there a way to set the values of a querystring using javascript?</p>

<p>My page has a filter list that when clicked, it will alter the in-page results pane on the right hand side. </p>

<p>I'm trying to update to the querystring values of the url, so if the user leaves the page, then clicks the "back" buttons they'll be return to the last filter selection set. </p>

<p>For example:<br>
    Landing: foo.html<br>
    Click 1: foo.html?facets=bar<br>
    Click 2: foo.html?facets=bar|baz<br>
    Click 3: foo.html?facets=bar|baz|zap  </p>

<p>Is this possible?</p>
