    Unable to validate data after idle

    Im developing an ASP.NET application used for maintinance purpose and
    it may be idle for some ours. The application crash with the error
    shown below when the user click on some contol in the appliaction.
    This crash occurs on every clients at same time, event for the client
    at the local server. I added some logging to the Application_Err or
    method that contains following:
    Exception of type System.Web.Http UnhandledExcept ion was thrown.
    at System.Web.UI.P age.HandleError (Exception e)
    at System.Web.UI.P age.ProcessRequ estMain()

    +IExecutionStep .Execute()
    at System.Web.Http Application.Exe cuteStep(IExecu tionStep step,
    Boolean& completedSynchr onously)

    We have deployed the application on a lot of plats without any problem
    so it seems that we have some problem with the setting for the IIS.
    The IIS is windows standard compinent in Windows server 2003. Note
    that we using .Net framework 1.1 and the serve also have .NET
    framework 2.0 installed.

    Information from the Webclient:

      it may be idle for some ours.
      <snip>

      Is it not simply that the clients' Session has timed out...?

      Easy enough to code round this by interrogating the IsNewSession property of
      the HttpSessionStat e object:

      I almost always construct a base page which has this check built into it and
      then inherit all subsequent pages from that instead of the default Page
      object...

          Thank you for answer.

          But why should this happen at same time for every clients?

          I think it seems that the server loosed some inormation about the
          viewstate or something.

              Maybe your web app recycled...? Are there any entries in the web server's
              Event Log which would confirm this...?

                          by default the viewstate is encrypted. the key is autogenerated when the
                          appdomain starts up. it appers in your case when the app domain is
                          recycled (after idle time) a new key is generated (maybe you have more
                          than 1 nic on the server and a different mac address is picked). you can
                          set the machineKey in the web config to prevent this.
