Hi, This is a user server, which is something powered by cloudvars and a host, How it works is simple: It funnels data through cloud variables with a user id so not all users get the data, and in response the user sends more instructions to the host. Here's an example: A client wants to get an item from the list with the address 1567, but that data is not in his list, so he sends an instruction to the host asking for that item, the host recieves the message and automatically grabs the item with the address 1567 and then splits and encrypts the data then sends it with the user's id, 103 to the user.
