curl имеет опцию connect-to
--connect-to <HOST1:PORT1:HOST2:PORT2>
For a request to the given HOST:PORT pair, connect to CONNECT-TO-HOST:CONNECT-TO-PORT instead. This option is suitable to direct requests at a specific
server, e.g. at a specific cluster node in a cluster of servers. This option is only used to establish the network connection. It does NOT affect the host-
name/port that is used for TLS/SSL (e.g. SNI, certificate verification) or for the application protocols. "host" and "port" may be the empty string, meaning
"any host/port". "connect-to-host" and "connect-to-port" may also be the empty string, meaning "use the request's original host/port".
This option can be used many times to add many connect rules.
