                    --  default: CONNECT="c,i,m,h,y,v,s,d:*:*:*"

This parameter controls the order of trials for connection to the target server using several connection method as followings:

connType:

cache	-- CACHE search (without connection)
icp	-- via a PROXY hinted by ICP server
proxy	-- via a PROXY server
master	-- via a PROXY or a MASTER-DeleGate server
https	-- via a SSLTUNNEL (SSL tunnel on HTTP)
yymux	-- via a YYMUX server
vsap	-- via a VSAP server
direct	-- direct connection to the target server
socks	-- via SOCKS servers
udp	-- by UDP
None	-- don't connect

Each connection type can be abbreviated by the first character as {c,i,m,d,v,s,u} respectively.
If ProtoList and dstHostList are given, this control is applied only to the protocols and hosts included in the lists. For example, to use cached data in a host which is not connected to external networks, specify as CONNECT="cache:*:!./@".

Note: In current implementation, "cache" will be tried first anyway if it is included in the connSeq.

A combination of -Pport with CONNECT=udp relays from TCP client to UDP server, and -Pport/udp with non-udp CONNECT relays from UDP client to TCP server.
