/**
* This function does a redirect to a specified url.
* IE works perfectly just using window.location.href buy Firefox fails.  This is why... Its because Firefox for some reason
* does not fire immediately and needs a small delay in order to work.  This script has a 1 second delay which works
* 100% in IE and firefox.
* 
* Usage example:
*   <input type='button' name='cancel' value='Cancel' onclick="do_redirect("http://domain.com"); />
