#       src             "socket" when using scgi_socket, or anything else when using scgi_port
#       socket          rTorrent's rpc socket (scgi_local)      - using scgi_local      - needed, when "src" is set to "socket"
#       diff            "yes" for using bps for upload and Bps for download, or anything else for using Bps for both

# Configuration example
