ASP.NET 会话状态在 Web.config 和 Global.asax 中不起作用

Question

I have Admin Page wherein I use to do some update work for my site. The problem is the session will expire within a minute or 30 seconds and will logout the user. I have set the Session in Web.Config of the root folder as well as in the Web.Config inside the Admin folder but still the session gets expired soon. I have set it to 60 minutes but it only lasts for 30 seconds or within a minute. Here is my web.config content of root folder

<sessionState timeout="60" mode="InProc" 
      cookieless="false"></sessionState>


    <customErrors mode="Off">
    </customErrors>
    <trace enabled="true" />
    <authentication mode="Forms">
               <forms
    protection="All"
    timeout="120"
    domain="www.marpallichande.in"
    slidingExpiration="true"
    name="auth_cookie" />  

    </authentication>

and this is my setting of web.cofing file inside the Admin folder

<sessionState timeout="60" mode="InProc"
      cookieless="false"></sessionState>

and this is my setting in Global.asax file under Session_Start method

Session.Timeout=60;

I am not getting how the session is getting expired so soon or is there any other reason for been getting logged out other than session.

Answer 1

sessionState timeout value is in minutes. I would start by removing Session.TimeOut (and any other timeout values except sessionState timeout, leave it as it is and give it a try. Also, not sure why you have two config files? Do they have same settings?

I have a similar setup but just one config file with

<sessionState mode="InProc" cookieless="false" timeout="10" /> 

setting it to 10 minutes.

Answer 2

write <sessionState mode="InProc" cookieless="false" timeout="10" /> in the global web.config file of your application.

define Session_OnEnd event by adding a subroutine named Session_OnEnd to the Global.asax file. The Session_OnEnd subroutine is run when the method has been called or when the session has expired. A session expires when the number of minutes specified by the Timeout property passes without a request being made for the session.

The Session_OnEnd event is supported only when the session state Mode property is set to InProc.

Session_onEnd event can be defined in global.asax as:

public void Session_OnEnd()
{
  // do your desired task when the session expires
}

Answer 3

Check the root web.config for a session state setting such as:
//Timeout is in minutes
//Note for using the global.asx about InProc: SessionStateModule.End Event

The Session_OnEnd event is only supported when the session-state HttpSessionState.Mode property value is InProc, which is the default. If the session-state Mode is set to StateServer or SQLServer, then the Session_OnEnd event in the Global.asax file is ignored. If the session state Mode property value is Custom, then support for the Session_OnEnd event is determined by the custom session-state store provider.

<system.web>
<sessionState mode="InProc" cookieless="false" timeout="30" />
</system.web>

You should only have this defined in 1 location.

Answer 4

if page logout after some seconds automatically that is because of session expire

 <sessionSate mode="StateServer" cookieless="false" timeout="940"/> 

write the code in web.config

I find the solution from enter link description here

Answer 5

There is a setting in IIS as well that may need to be updated, the "idle timeout" setting. The difference is explained here .

By default Idle Timeout is set to 20 minutes, so you will want to set that to 180. This can be done by going into IIS > Application Pools > Right Click Your App Pool > Advanced Settings:

I had the same issue in my ASP.NET MVC web project. Using the following method to set the session duration in the Global.asax.cs file works:

public class ApplicationName : System.Web.HttpApplication
{
    protected void Session_Start(object sender, EventArgs e)
    {
        /* Sets the session duration to 60 minutes. */
        Session.Timeout = 60;
    }
}
