 | 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 hostname/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. |
