#

#	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"

#	ip		rTorrent's ip address			- using scgi_port	- needed, when "src" is NOT set to "socket"

#	port		rTorrent's scgi port (scgi_port)	- using scgi_port	- needed, when "src" is NOT set to "socket"
