SessionState timeout problem

Discussion in 'ASP .Net' started by Mikko Penkkimäki, Sep 6, 2004.

  1. Hi

    Looks like I can not change Web page's timeout setting. In practise it's all
    the time 20 minutes - no matter what I do.

    I have this kind of setting in web.config:

    With this settings program goes to Global.asax's Session_End() function
    after 1 minute but the session is still running after this. It's only after
    20 minutes when the session really stops.

    I have tried to change the timeout setting in Machine.config also >> No
    I have even booted my computer after I have made change to the setting -
    just in case if something is still running in memory. >> No help.

    That 20 minutes settings has to be somewhere hidden, but where? Couldn't
    find it from IIS either.

    I have Windows XP Pro and Visual Studio .NET 2003.

    Please help me.

  2. How are you determining that the session is still running? Is it just that
    you dont go back to the login page or something like that?

    Also, keep in mind that it's 20 minutes from the last activity - ie, it's a
    sliding timer not an absolute one.

  4. Hi

    There's no login page in the software. New session is created for every new
    user from "HttpContext.Current.Session.SessionID". This SessionID is used
    for loading and saving user dependent session data (for

    I can see that the session is still running because the SessionID is still
    the same and all user dependent data is still in session. When I change to
    another page in the software after about 20 minutes, the SessionID has been
    changed. Session data is also empty - of course.

    I have now changed the SessionState's mode to "StateServer". I have read
    from the Web that it's not as buggy as "InProc". Still no effect in my

    My problem is that there is a need that the session lasts hours - not 20
    minutes. I have changed SessionState's timeout to "120" in Web.config and
    Machine.config. I also found setting from IIS: Web page Properties >>
    Configuration... >> Options: Enable session state, Session timeout. I
    changed also this to 120. Still the session is lost after about 20 minutes.

    I have tried to find answer to this from the Web. I haven't found any answer
    yet but I have found many other programmers who have faced the same problem:
    Sessions just don't last long. Is there any way to get over this?

    You were in the right place when you poked around in IIS.

    Go to the website in question, right-click and choose "Properties".
    Click on the "Home Directory" tab
    Click on the "Configuration" button
    Click on the "App Options" tab on the pop-up window
    Choose the session timeout you wish. As you can see on this screen, the
    default value built into IIS 5.0 out of the box is 20 minutes.

    Sorry to open up a thread that's a few years old but I'm having the same problem described above with no luck resolving it.
    I've changed

    sessionstate to 120mins
    added machinekey to the web.cofig
    iis app pool timeouts to 120mins
    sessionstate properties from iismanager-app config

    I've done everything I can think of but sessions are still being terminated after about 20 minutes. This doesn't seem to be on a sliding scale either as I can be working on the page for a few minutes and when I go to another page I get kicked back to the 'Default.aspx' screen.

    Any suggestions are appreciated

    Q: Why does the SessionID remain the same after the Session times out or abandoned?
    A:Even though the session state expires after the indicated timeout period, the session ID lasts as long as the browser session. What this implies is that the same session ID can represent multiple sessions over time where the instance of the browser remain the same.

    Great you even booted your computer after you have made change to the setting, great man , but you missed one single thing, you must have reinstalled the windows and that would have surely worked.
