Why TIWServerController.IWServerControllerBaseNewSession called more than once

Hello everybody,


I use IW 15.2.69 with delphi 11

In debug mode 

I'm wondering why TIWServerController.IWServerControllerBaseNewSession is called more than once within the same session.

So,

ASession.Data := TIWUserSession.Create(nil, ASession) is called more than once.

and thus

IWUserSessionBaseCreate is also called more than once.

App is working even like that but is it normal ?

Any idea why ?

Help would be appreciated,

Kind regards
