Sites that save and restore shopper IDs by means of URLs or cookies should use the PutShopperID method of the Page object instead of the PutShopperID method of StandardSManager. Sites using the AUO do not require these methods.
The PutShopperID method stores a shopper ID in the cookie and/or a URL/SURL, depending on the mode in which the StandardSManager is running.
StandardSManager.PutShopperID(Context, ShopperID)
This method is included for compatibility with previous releases.
