Me neither. I myself seldom use Socks for HTTP protocol. Thus
I did not know, and am surprised to know that even recent WWW
browsers does not support SocksV5.
Maybe authentication mechanism introduced in SocksV5 is not so
attractive for HTTP/TCP clients while the disadvantage by its extra
round-trip time for authentication is not negligible.
I thought the attractive feature of SocksV5 is that domain name
resolution can be delegated to Socks server. But I'm surprised to
know that SocksV4 also extended to do such delegation.
It might be worth being supported by DeleGate although I don't
know how many SocksV4 clients support this extension.

Sorry but I have no experience with other SOCKS servers other than
DeleGate and NEC's.
