This is to be used with History.js. It removes all the hash stuff added when a user uses an HTML4 browser

redirect.js

var hashUrl = window.location.hash;

if(hashUrl !== '') {
    var url = hashUrl.replace('#',''); // remove #
    var redirectUrl = window.location.protocol+'//'+window.location.host;
    var path = window.location.pathname;
    url = url.split('_suid')[0]; // remove everything after this
    
    // if there are no vars, remove the ?&
    if(url.indexOf('?') <= (url.length+2)) {
        url = url.replace(/\?|&/g, '');
    }
    // if there is a '.' then remove the 
    // last path
    if(url.indexOf('.') === 0) {
        // remove the '.'
        url = url.replace('.', '');
        // remove the last path
        path = path.slice(0,path.lastIndexOf('/'));
    }
    // create the new url to redirect to
    redirectUrl += path+url;
    window.location.href = redirectUrl;
