change server message when max connection/session has reached

[Point]

Hello,

How to customize server message when max connection/session has reached ?

default message like this : Can not create more sessions: [Max= 3, Current= 3]

and i want to change with message like this :

"Currently this website is full of visitors, please wait a little longer."

hope that message only display when connection has been reached, but could display native exceptions message when other exceptions raise.

Thank you in advance.

Does uniGUI have Error Code for every Exception or Does UniGUI have Constanta Message unit file like DBConst.pas so we could customize Exception Message

procedure TUniServerModule.UniGUIServerModuleException(
  Sender: TUniGUIMainModule; AException: Exception; var Handled: Boolean);
begin
  if AException.ErrorCode = 10001 then AException.Message = 'bla bla bla...';
end;
