  Session state doesn´t renew

  Apr 12, 2012 09:38 PM|LINK

  Hi, i have the next structure in my application:

  1 i've a user control, it has a menú that rebind every control load using user info stored in session state and a exit button

  2 i've a master page that have a image head, and body content (only visual no controls, any code)

  3 i've pages based in the master page that include, each one, the user control. this page have a UpdatePanel like this:

  <form id="form1" runat="server">
      <asp:ScriptManager ID="ScriptManager1" runat="server">
      </asp:ScriptManager>
      <asp:UpdatePanel ID="UpdatePanel1" runat="server">
          <%--Form content --%>
      </asp:UpdatePanel>
  </form>

  Then, i got a problem the application worws fine with session time in develoment server (starting with visual studio), but whn i upload compiled web application to web server, session time is corrupted, it close very fast or not close, provider does ´t make a memory pool for my application, then the first solution that ocured to me is renew session automatically each time to time.

  I already try to use this examples for renew session:

  1. Using javascript code for create a setTime of AJAX that calls a ascx file as a javascrip implements IRequireSessionstate web method, passing on pipe session. the script works fine (it add a new script tag to head using ashx file) but session never refreshed. how explain this guy: http://geeks.ms/blogs/jalarcon/archive/2008/06/11/c-243-mo-evitar-que-la-sesi-243-n-caduque-por-inactividad.aspx
  2. Using a Timer + UpdatePanel<Trigger> combination for execute server code that make some change to session state (create a innecesary variable, for example)  each time to time, this works in my case i created a counter and show it to the user each Tick, but session never refreshed.
  3. Using a combination of non visible iframe that implemets postbacks each time to time like that:
     

     if (User.Identity.IsAuthenticated)
        {
           // Refresh this page 60 seconds before session timeout, effectively resetting the session timeout counter.
           MetaRefresh.Attributes["content"] = Convert.ToString((Session.Timeout * 60) - 180) + ";url=KeepSessionAlive.aspx?q=" + DateTime.Now.Ticks;
           WindowStatusText = "Last refresh " + DateTime.Now.ToShortDateString() + " " + DateTime.Now.ToShortTimeString();
        }

     
     
     and webconfig file configuration like that:
     

     <authentication mode="Forms">
         <forms name="Pharsat" timeout="30" protection="All" loginUrl="~/Login.aspx" slidingExpiration="true" />
     </authentication>
     <sessionState mode="InProc" cookieless="false" timeout="30"/>

  in the cases, i implements the code into user control. all codes do what it should do, but neither renew session.

  I remember had readed in a post that this can be because i am usen updatepanel in a page.

  Then, can you help me? i need find a code for renew session trasparent by user, how this page when i writing the post, without use navigator cookies. any idea?

  Thank you very much, Pharsat.
