  why web pages expire when do not active in about 4 minutes

  Jun 08, 2020 02:13 AM|test0101|LINK

  dear fiend

  The first, thanks the friends in this forum has help me alot of to build the application website ASP.net C#.

  at moment, I finish create  the webapp ( at  you can login with demo/demo), but I'm facing a problem is when i open the web, in about 4 minutes if I don't have any actions on page then click on any  link on  website, it will reditect to login page.

  my web.config:

  <?xml version="1.0" encoding="UTF-8"?>
  <configuration>
    <configSections />
    <appSettings />
    
    <system.web>
      <httpRuntime executionTimeout="999999" />
      <compilation debug="true" targetFramework="4.5.2" />
    
      <trust level="Full" />
      <authentication mode="Forms" />
       
  	 <sessionState timeout="60"></sessionState>  
  
    <customErrors mode="Off" defaultRedirect="" />
  
  <machineKey validationKey="308A5193B77D18BB33F286DCC941A54331AE8D000104EAC1DB843D98B1CB457AF9A813B4D5D7D77220987AC8EA478401577194FC20E6CCE8ACEC159C5C59D754" decryptionKey="46C25F7D8BFDE6DAF886AEC2706EFA6A2706C43C752B69C82D5B13A29EA246C1" validation="SHA1" decryption="AES" />
  
    </system.web>
  
    <system.webServer>
      <directoryBrowse enabled="true" />
          <defaultDocument>
              <files>
                  <clear />
                  <add value="default.aspx" />
                  <add value="Default.htm" />
                  <add value="Default.asp" />
                  <add value="index.htm" />
                  <add value="index.html" />
                  <add value="iisstart.htm" />
              </files>
          </defaultDocument>
    </system.webServer>
    
  </configuration>

  In my code I use masterpage (main.master) and session:

  Login.cs

  if user Login susscess:

  HttpContext.Current.Session.Timeout = 60;
  HttpContext.Current.Session["UserName"] = txtUserName.Text;

  In main.master i use:

  <asp:ScriptManager id="toolScriptManageer1" runat="server" EnableHistory="true" EnablePartialRendering="false" EnablePageMethods="true"> </asp:ScriptManager>

  and in Main.master.cs:

   protected void Page_Load(object sender, EventArgs e)
          {
              if (HttpContext.Current.Session["UserName"] == null)
              {
                  Response.Redirect("~/login.aspx");
                  Context.ApplicationInstance.CompleteRequest();
              }
                          
              if (!IsPostBack)
              {               
                    DataTable dt = this.GetData(0);
                    PopulateMenu(dt, 0, null);               
              }
           
              
          }

  Hi,

  My first move would be to show HttpContext.Current.Session.SessionID. If the value changed it would confirm you are loosing the session for some reason. If I remember it is written  to the Windows log out of box or at worst you can activate that. Or maybe you are using load balanced servers?

  Edit: for example https://stackoverflow.com/questions/829392/how-to-discover-the-reason-of-asp-net-application-restart  or https://docs.microsoft.com/en-us/previous-versions/iis/6.0-sdk/ms525613(v%3Dvs.90) at the IIS level or https://docs.microsoft.com/en-us/aspnet/web-forms/overview/older-versions-getting-started/deploying-web-site-projects/logging-error-details-with-asp-net-health-monitoring-cs at the ASP.NET level.

  Hi test0101,

  test0101

  Have you restarted your app during this time?

  <authentication mode="Forms" />
       
  	 <sessionState timeout="60"></sessionState>

  Forms Authentication is not based on session. It is managed via an authentication cookie. It is unlikely that the session is expiring. More likely that the forms authentication ticket is. Try setting a value for the forms auth timeout:

  <authentication mode="Forms">
    <forms loginUrl="~/login.aspx" timeout="60" slidingExpiration="true" />
  </authentication>

  Change login.aspx to the page where the user logs in.

  Hi

  if I added this to web.config:

  <authentication mode="Forms">

  <forms defaultUrl="~/default.aspx" loginUrl="~/Login.aspx" slidingExpiration="true" timeout="60"></forms>

  </authentication>

  it's apprear error:

  Configuration Error

  Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.
  
  Parser Error Message: The configuration section cannot contain a CDATA or text element.
  
  Source Error:  An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

  Check that you haven't mistakenly added some other characters to the web.config when you added that section.
