        var aspForm = $("form[id=aspnetForm]");

        var oldPostbackUrl = aspForm.get(0).action;

        var currentSourceValue = GetUrlKeyValue("Source", true, oldPostbackUrl);

        var newPostbackUrl = oldPostbackUrl.replace(currentSourceValue, "https%3A%2F%2Fint%2Eapac%2Esp%2Ewp%2Ecorpintra%2Enet%2Fsites%2F04400%2FDashboard%2520UAT%2FSitePages%2FProjects%2Easpx");
