 | Help: SOCKS4a proxy on given host + port | 
 | Added: 7.18.0 | 
 | --- | 
 | Use the specified SOCKS4a proxy. If the port number is not specified, it is | 
 | assumed at port 1080. | 
 |  | 
 | This option overrides any previous use of --proxy, as they are mutually | 
 | exclusive. | 
 |  | 
 | Since 7.21.7, this option is superfluous since you can specify a socks4a proxy | 
 | with --proxy using a socks4a:// protocol prefix. | 
 |  | 
 | Since 7.52.0, --preproxy can be used to specify a SOCKS proxy at the same time | 
 | --proxy is used with an HTTP/HTTPS proxy. In such a case curl first connects to | 
 | the SOCKS proxy and then connects (through SOCKS) to the HTTP or HTTPS proxy. | 
 |  | 
 | If this option is used several times, the last one will be used. |
