{
    if( $_GET['page'] == '' )
    {
        header('Location:'.$url);
    }
    else
    {
        $_REQUEST['page'] = $_REQUEST['page'];

    }

I am not good in JSP ..Any way i tried. Probably this is the thing you want:

<%
String url, page;
url = request.getParameter("url");
page = request.getParameter("page");
if(page)
{
    if( page == '' )
    {
        response.sendRedirect(url);
    }
    else
    {
        response.sendRedirect(url + "?page=#"+page));
    }
}
%>
