Hi,

 I'm unable to extend the session time out from 20 minutes to 60 minutes. I'm using the forms authentication and my session state is set to state server. I have made the changes in my web.config for authentication and session state from 20 to 60 and still session times out after 20 minutes. I'm using .Net 3.5 in my application.

 Thanks

I'm not sure if IIS session timeout applies to asp.net or only asp, but it's worth changing the session timeout in IIS to 60 minutes and see if that helps.

 you mention session time out in web config  as given below

<sessionState mode="InProc" stateConnectionString="tcpip=72.41.47.186:42424" cookieless="false" timeout="1440"/>

if not solved set time out in  iis 

i hope it helps you

If  your appliction is in ASP. You need to configure IIS Session Timeout.

If it's ASP.NET application, web.config overrides IIS session timeout.

Do you have multiple web.config in your project?

If root folder of an application has any subfolders with web.config files in there, the settings of those files will override the settings of the file in the root directory.

 Aditya, I'm using the State server. here is my web.config settings

<sessionState mode="StateServer" stateConnectionString="tcpip=127.0.0.1:42424" timeout="60"/>

<authentication mode="Forms">
      <forms loginUrl="~/Public/Login.aspx" defaultUrl="~/Customer/Default.aspx" timeout="60"/>
    </authentication>

Session has nothing to do with forms authentication. You may be overriding forms authentication timeout value in code. Check this..

 Hi  ajay.kukreja,

 There are few possible option where you can set the session time out.

1. In Web.config like..
       <sessionState mode="InProc" timeout="15" cookieless="true" />

2. In Session_Start event in Global.asax like....
       Session.TimeOut=15;

3. In IIS Setting you can also set default session timeout.

       a. open IIS start==run==inetmgr  and press enter.
       b. Right Click on "Default Web Site" go in Propertied
       c. Select Asp.Net, click on "Edit Configuration" Button 
       d. Select "State Management" in new popup window
       e. Change the session timeout here.
