C#.NET How to set session time out to 6 hours with forms authentication?

In my application I use Forms Authentication and 开发者_运维技巧sessions. How do I take care that the user is logged out after a period of 6 hours?

In my web.config I set the sessions time-out to 360 minutes. But after a period of 10 minutes of inactivity I have to login again.

I also set my forms authentication timeout to 360 minutes. What is it I am doing wrong?

There are some other timeout values that will affect session time out. One of them that comes to my mind is Worker Process Timeout(that is set from IIS). Worker Process's default time out is 20 mins, so if there is no activity in your site for 20 mins the worker process will end and causing your session to end if you are using session in InProc mode. So getting Worker Process's timeout value to 360 minutes is what you may need as well.

try this setting:

<authentication mode="Forms"> <forms timeout="360" slidingExpiration="true"/> </authentication>

couple things to check also:

• if your FormsAuthenticationTicket is created with a lower cookie timeout value, that could override

• if the application pool "shutdown worker processes" interval is lower, that would reset the state earlier

Instead of setting a session timeout, you could implement a mechanism to keep the session alive, eg: refresh the page or make an ajax call etc.

You could add to this by implementing a maximum login time, that can be checked etc

You need to adjust timeout and slidingExpiration:

<authentication mode="Forms">
    <forms requireSSL="false"
        defaultUrl="Default.aspx"
        loginUrl="Login.aspx"
        path="/"
        slidingExpiration="false"
        timeout="360"
        name=".ASPXFORMSAUTH">
    </forms>
</authentication>

Are you using InProc Sessions? (That's the default on ASP.net AFAIK) In that case, check if your Application Pool recycles, as this will kill all sessions. I don't have an IIS to check, but I believe it's configured to shut down an Application Pool if it's idle for a given time - if this is your development Server, maybe you've been idle for too long so that the AppPool recycles and your InProc Sessions are killed?

I'm not sure how easy it is to quickly implement stateserver or sqlserver instead of inproc, but here is the MSDN Page about Session State.
