1 Long: socks4 2 Arg: <host[:port]> 3 Help: SOCKS4 proxy on given host + port 4 Added: 7.15.2 5 Category: proxy 6 Example: --socks4 hostname:4096 $URL 7 --- 8 Use the specified SOCKS4 proxy. If the port number is not specified, it is 9 assumed at port 1080. Using this socket type make curl resolve the host name 10 and passing the address on to the proxy. 11 12 This option overrides any previous use of --proxy, as they are mutually 13 exclusive. 14 15 Since 7.21.7, this option is superfluous since you can specify a socks4 proxy 16 with --proxy using a socks4:// protocol prefix. 17 18 Since 7.52.0, --preproxy can be used to specify a SOCKS proxy at the same time 19 --proxy is used with an HTTP/HTTPS proxy. In such a case curl first connects to 20 the SOCKS proxy and then connects (through SOCKS) to the HTTP or HTTPS proxy. 21 22 If this option is used several times, the last one will be used. 23
