Provide a custom address for a specific host and port pair. Using this, you
|
||
|
|
can make the curl requests(s) use a specified address and prevent the
|
||
|
|
otherwise normally resolved address to be used. Consider it a sort of
|
||
|
|
/etc/hosts alternative provided on the command line. The port number should be
|
||
|
|
the number used for the specific protocol the host is used for. It means
|
||
|
|
you need several entries if you want to provide address for the same host but
|
||
|
|
different ports.
|
||
|
|
|
||
|
|
By specifying '*' as host you can tell curl to resolve any host and specific
|
||
|
|
port pair to the specified address. Wildcard is resolved last so any --resolve
|
||
|
|
with a specific host and port is used first.
|
||
|
|
|
||
|
|
The provided address set by this option is used even if --ipv4 or --ipv6 is
|
||
|
|
set to make curl use another IP version.
|
||
|
|
|
||
|
|
By prefixing the host with a '+' you can make the entry time out after curl's
|
||
|
|
default timeout (1 minute). Note that this only makes sense for long running
|
||
|
|
parallel transfers with a lot of files. In such cases, if this option is used
|
||
|
|
curl tries to resolve the host as it normally would once the timeout has
|
||
|
|
expired.
