In 13 such a case curl first connects to the SOCKS proxy and then connects (through 14 SOCKS) to the HTTP or HTTPS proxy. Hence pre proxy. 15 16 The pre proxy string should be specified with a protocol:// prefix to specify 17 alternative proxy protocols. Use socks4://, socks4a://, socks5:// or 18 socks5h:// to request the specific SOCKS version to be used. No protocol 19 specified makes curl default to SOCKS4. 20 21 If the port number is not specified in the proxy string, it is assumed to be 22 1080. 23 24 User and password that might be provided in the proxy string are URL decoded 25 by curl. This allows you to pass in special characters such as @ by using %40 26 or pass in a colon with %3a. 27
