| For a request to the given HOST1:PORT1 pair, connect to HOST2:PORT2 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. "HOST1" and "PORT1" may be the empty string, meaning "any |
| host/port". "HOST2" and "PORT2" may also be the empty string, meaning "use the |
| request's original host/port". |
| |
| A "host" specified to this option is compared as a string, so it needs to |
| match the name used in request URL. It can be either numerical such as |
| "127.0.0.1" or the full host name such as "example.org". |
| |
| This option can be used many times to add many connect rules. |
