    response.addheader("content-disposition", 
        "attachment;   filename=" + httputility.urlencode((file.name), system.text.encoding.utf8));
    response.addheader("content-length", file.length.tostring());
    response.contenttype = "application/octet-stream";

    response.writefile(file.fullname);
    response.flush();
