IE did not set document.referrer

INFO: Internet Explorer Does Not Send Referer Header in Unsecured Situations

When linking from one document to another in Internet Explorer 4.0 and later, the Referer header will not be sent when the link is from an HTTPS page to a non-HTTPS page. The Referer header also will not be sent when the link is from a non-HTTP(S) protocol, such as file://, to another page.

Try this

<script type="text/javascript" >            
function redirect(url) {
    if (/MSIE (\d+\.\d+);/.test(navigator.userAgent)){
        var referLink = document.createElement('a');
        referLink.href = url;
        document.body.appendChild(referLink);
        referLink.click();
    } else {
        location.href = url;
    }
}
</script>
