# `--connect-to`
|
|
|
|
For a request intended for the `HOST1:PORT1` pair, connect to `HOST2:PORT2`
|
|
instead. This option is only used to establish the network connection. It does
|
|
NOT affect the hostname/port number that is used for TLS/SSL (e.g. SNI,
|
|
certificate verification) or for the application protocols.
|
|
|
|
`HOST1` and `PORT1` may be empty strings, meaning any host or any port number.
|
|
`HOST2` and `PORT2` may also be empty strings, meaning use the request's
|
|
original hostname and port number.
|
|
|
|
A hostname 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`.
|
|
|
|
Example: redirect connects from the example.com hostname to 127.0.0.1
|
|
independently of port number:
|
|
|
|
curl --connect-to example.com::127.0.0.1: https://example.com/
|
|
|
|
Example: redirect connects from all hostnames to 127.0.0.1 independently of
|
|
port number:
|
|
|
|
curl --connect-to ::127.0.0.1: http://example.com/
