This is retail implementation for getting L2OFF data for site w/o direct connections to database, etc. NC Soft uses it for all gameservers. You can try to check it. If you want to use it for L2J server then you need implement responce for ProtocolVersion -3 in gameserver code. Many times ago i’m used it for getting info from L2OFF servers and for own project site. As example L2ON.NET still uses it.
