Application Times Out, Forcing Users to Sign In Again

Problem

When running your application, you are unexpectedly sent back to the application’s main page (default starting page).  You may be asked to sign-in again from the application’s sign-in page.

This occurs because your application has timed out.  There are several reasons your application may time out:

• Application’s time out period was exceeded.  Applications built with Iron Speed Designer have a time out period set in the application’s Web.config file.  Once this period of inactivity is reached for a specific user, the user’s session is terminated.  The user must sign into the application again to continue using it.

• Microsoft IIS web server was reset.  When the web server is reset, all applications must be restarted, and all previous session information is lost.  This restarts your application, and users must sign in again.

• ASPNET user was reset.  The ASPNET user account is key in most applications.  Resetting the ASPNET user and its attendant permissions causes your application to restart.

• Application’s Web.config file was modified.  Changing your application’s Web.config file causes your application to restart.  Also if you have a Web.config file at the root where you deployed your application, then it might overlap or try to over write the application's Web.config, causing your application to restart.

• Server machine’s time out period was exceeded.  There is a time out setting in your server’s Machine.config file.
