Disable users timeouts

please, can any one tell me in details how can i disable timeout feature. acctually i dont want users to be timeout if they are not doing any thing on site. i increase the time of timeouts but its not a perminent solution. please tell me.....

Vibe streamer has a hidden frame that keeps updating when the user isn't doing anything in order to keep the user from getting timeouts. In some cases you can still get a timeout though, mostly due to connections being lost for a few seconds,. What browser do you run by the way?

yes Siit your are right, i noticed what u said, its realy belongs to connection problem most of the time......well its mean , there is nothing i can do, np...............by the way i use Internet Explorer..........
