This String is used to separate values in the URL. This separator is not configurable; its value is a single slash ("/"). For example, in the URL:

CopyC#

http://localhost:8080/products/Red-Merlot-Cherry/_/N-8025+4294967278

The '/' in the "/Red-Merlot-Cherry/" is the separator. This character must be a safe URL encoded character because the API does not UrlEncode this character.
