get url params 15.1.5

[MrSpock]

Another idea is not to put any code in user session unit

Code:

in ServerController.OnGetMainForm put

  if WebApplication.RunParams.Count>0
  then
  begin
     if WebApplication.RunParams[0]='steg'
     then
        vmainForm:=TIWForm9.Create(WebApplication)
     else
        vmainForm:=TIWForm2.Create(WebApplication)
  end
  else
     vmainForm:=TIWForm2.Create(WebApplication)  //usual main form
