Hy guys,
some questions about a js that i must include in my jsp :
I read with this javascript the cooki write by java cookie this is the code java in the jsp:

<%

Date now = new Date(System.currentTimeMillis());

DateFormat formatter = new SimpleDateFormat("dd/MM/yyyy hh:mm:ss.SSS");


String date = formatter.format(now);

Cookie cookie_registrazione = new Cookie("RegStep1_cookie", date);

response.addCookie(cookie_registrazione);


%>
now i must include a file js to read this cookie ok??


var nome = "RegStep1_cookie";

if (document.cookie.length > 0) {
alert("in document");
c_start = document.cookie.indexOf(nome + "=");
if (c_start != -1) {
c_start = c_start + nome.length + 1;
c_end = document.cookie.indexOf(";", c_start);
if (c_end == -1) c_end = document.cookie.length;

ret_cookie = unescape(document.cookie.substring(c_start, c_end));


return ret_cookie;

}
}
