Very simple code in ASP, works for other devices (Some motorola).
Nokia accepts the cookie, but if the device not used for ~3 days (powered off) the cookie disappears.
No, I didn't press clear all cookies option.
The time on the server is OK.
The cookie survives power cycle, so maybe it's just 3 days.

Snippet of the code:

<%
Response.Expires=0
Response.ExpiresAbsolute=#May 31,1996 13:30:15#
Response.ContentType = "text/vnd.wap.wml"
Response.Buffer = true
.....
Response.Cookies("user")=CStr(rs.Fields("WapUserID"))
Response.Cookies("user").Expires=Now()+356
%>
<?xml version="1.0" encoding="ISO-8859-8"?>
<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN" "http://www.wapforum.org/DTD/wml_1.1.xml">
<wml>
...

End snippet

The questions are:
1. Is this a know bug.
2. Any official firmware update to make it work.
3. Any other places to ask.

Thanks in advance.
