Enabling Session State Persistence (IIS 6.0)
You can enable session state persistence for ASP applications. If you enable session state persistence, the server will create a new Session object for each connection and session state will be accessible, session storage will be allowed, Session_OnStart and Session_OnEnd will occur, and ASPSessionID cookie will be sent to the client. If you do not enable session state persistence, state access and storage are not allowed, events are not processed, and no cookie is sent. By default, session state persistence is enabled with the session timeout at 20 minutes. The corresponding metabase property is AspAllowSessionState Metabase Property.
Important You must be a member of the Administrators group on the local computer to perform the following procedure or procedures. As a security best practice, log on to your computer by using an account that is not in the Administrators group, and then use the runas command to run IIS Manager as an administrator. At a command prompt, type runas /user:Administrative_AccountName "mmc %systemroot%\system32\inetsrv\iis.msc".
