This is the default value for the TIdHTTP.HandleRedirects property.

Id_TIdHTTP_HandleRedirects = False;

Id_TIdHTTP_HandleRedirects is the default value for the TIdHTTP.HandleRedirects property. This is used in the class definition and the constructor. This is done to prevent problems with Delphi's form streaming mechanism. Changing this value will change the default value for that property.
