Iis 6 session timeout not increase

Hi All,

I want to increase session timeout until 4 hours for my asp.net application.I am using iis 6 with window server 2003 r2.
I 've set configuration in iis 6-enable session state and put 240 minutes.
Moreover,i also set idle timeout setting to 240 minutes in application pool.

Web config i put <sessionState timeout=“240” cookieless=“false”/> under <system.web> but i still not able to increase the timeout until 4 hours.
It seem like stand until 1 hour then will not able to use the website already.

Anyone can advise for this issue.I been stucked for this problem quite a long time.:(Please help.Thanks!

Dear ashley8905 ,
your server is old so please update your hosting server.if you want to increased session time upto 4 hours then you can not achieved on window server.you must be take Linux server where you can increased session time.
