    I am afraid it shouldn't be 20 seconds. Check web.config sessionState element. What is the timeout value of this element? This value is in minutes. So set whatever the value you want not to expire the session.

    <sessionState  timeout="60"...

    But the default session timeout 20 mins sounds good compare to high timeout value. Because it eats up your memory...

    Write following statement in Sysetm.Web section of your Web.Config file

    <sessionState timeout="30"/>

    This will increase Session time upto 30 Minutes.

    in web config file check the session timeout value and change the value what u want.

    <sessionState mode="InProc" timeout="30"></sessionState>

    in that timeout value set the value u want.

    Session default timeout is 20 minutes.
    But if you want to change it then write this one in web.config.

    <sessionState timeout="40"></sessionState>

    The default session timeout for an ASP.NET application is 20 mins. You can change the web.config to increase the time out value.

    But I see your requirement as not to expire the uer session until the user does signout on his own.I don't know the context of your requirement . But for the session to maintain indefinitely until the user does signout ,just do a post back operation for every 15 mins as follows


    Add the following in the master page of the application

    // Add in the page load event
    if (!Page.ClientScript.IsStartupScriptRegistered("URLs"))
          string KeepAliveURL = String.Format("<input type='hidden' id='hdnKeepAliveURL' value={0} />", "KeepAlive.aspx");
          Page.ClientScript.RegisterStartupScript(this.GetType(),"URLs", KeepAliveURL,false);

     //KeepAlive.aspx is a dummy page in the application

    <script type="text/javascript">

           function sessionKeepAlive() {       
               var webRequest = new Sys.Net.WebRequest();
               setTimeout("sessionKeepAlive()",900000); //calls sessionKeepAlive every 900000 milli seconds(15 mins)

    Call sessionKeepAlive() in <body> onload() event of the page

    As your default session timeout is 20 mins , do the post back every 15 mins to keep the session alive

    Note: If the user closes the browser without doing signout ,the session is automatically killed within 20 mins as no post backs happen to keep session alive.

    From TMK555, if (!Page.ClientScript.IsStartupScriptRegistered("URLs")). <-- URLs is the script key.
