PHP/Javascript Form Reset upon page entry or back
<p>I have a standard PHP form that has a series of checkboxes, radio, selects and text.  The form works fine and proceeds to a search results page.  My problem is that when you click Back browser in any browser the search page shows the previous selects.  How do I ensure that the back button displays the form as if its the first time the visitor visits the page?</p>
