Extend the syntax of CURLOPT_RESOLVE strings: allow using a '+' prefix (similar to the existing '-' prefix for removing entries) to add DNS cache entries that will time out just like entries that are added by libcurl itself. Append " (non-permanent)" to info log message in case a non-permanent entry is added. Adjust relevant comments to reflect the new behavior. Adjust documentation. Extend unit1607 to test the new functionality. Closes #6294

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 will be 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 will be used first.
|
|
|
|
The provided address set by this option will be 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 will only make sense for long
|
|
running parallel transfers with a lot of files. In such cases, if this option
|
|
is used curl will try to resolve the host as it normally would once the
|
|
timeout has expired.

|
Support for providing the IP address within [brackets] was added in 7.57.0.
|
|
|
|
Support for providing multiple IP addresses per entry was added in 7.59.0.
|
|
|
|
Support for resolving with wildcard was added in 7.64.0.
|
|
|
|
Support for the '+' prefix was was added in 7.75.0.
|
|
|
|
This option can be used many times to add many host names to resolve.
