登录超时：在什么情况下你使用它们？

I'm wondering when login timeouts are being used, specifically when using same session (same browser session). On a number of sites I have completed recently I have added 60 minute timeouts and they seem to be causing problems, such as users are not able to fill out larger forms (like a resume submission--people don't think of copying their resume from another program or saving part way through). On one site, I have implemented a div/popup forcing the user to enter their password to continue in the current session, without having to login again.I'm wondering when login timeouts are being use
