+
+Use the specified proxy.
+
+The proxy string can be specified with a protocol:// prefix. No protocol
+specified or http:// it is treated as an HTTP proxy. Use socks4://,
+socks4a://, socks5:// or socks5h:// to request a specific SOCKS version to be
+used. (Added in 7.21.7)
+
+Unix domain sockets are supported for socks proxy. Set localhost for the host
+part. e.g. socks5h://localhost/path/to/socket.sock
+
+HTTPS proxy support works with the https:// protocol prefix for OpenSSL and
+GnuTLS (added in 7.52.0). It also works for mbedTLS, Rustls, Schannel and
+wolfSSL (added in 7.87.0).
+
+Unrecognized and unsupported proxy protocols cause an error (added in 7.52.0).
+Ancient curl versions ignored unknown schemes and used http:// instead.
+
+If the port number is not specified in the proxy string, it is assumed to be
+1080.
+
+This option overrides existing environment variables that set the proxy to
+use. If there is an environment variable setting a proxy, you can set proxy to
+"" to override it.
+
+All operations that are performed over an HTTP proxy are transparently
+converted to HTTP. It means that certain protocol specific operations might
+not be available. This is not the case if you can tunnel through the proxy, as
+one with the --proxytunnel option.
+
+User and password that might be provided in the proxy string are URL decoded
+by curl. This allows you to pass in special characters such as @ by using %40
+or pass in a colon with %3a.
+
+The proxy host can be specified the same way as the proxy environment
+variables, including the protocol prefix (http://) and the embedded user +
+password.
+
+When a proxy is used, the active FTP mode as set with --ftp-port, cannot be
+used.
+
+Doing FTP over an HTTP proxy without --proxytunnel makes curl do HTTP with an
+FTP URL over the proxy. For such transfers, common FTP specific options do not
+work, including --ssl-reqd and --ftp-ssl-control.
