This method is not intended to be called from application code.

The SaveSessionID method is called by the SessionStateModule object during the AcquireRequestState event. The SaveSessionID method stores the session identifier in either the URL (when cookieless session state is used) or in a non-expiring session cookie.

By default, the SessionIDManager places a unique session identifier into a non-expiring session cookie and sets the cookieAdded parameter to true.

For a cookieless session state, the SessionIDManager object inserts a unique session identifier into the current URL, redirects the browser to the new URL that includes the session identifier, and then sets the redirected parameter to true.
