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".
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".
The "hosts" specified to this optionare compared as strings, so it need to
match the string used in the request URL but 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.
