# `--anyauth`
|
|
|
|
Tells curl to figure out authentication method by itself, and use the most
|
|
secure one the remote site claims to support. This is done by first doing a
|
|
request and checking the response-headers, thus possibly inducing an extra
|
|
network round-trip. This is used instead of setting a specific authentication
|
|
method, which you can do with --basic, --digest, --ntlm, and --negotiate.
|
|
|
|
Using --anyauth is not recommended if you do uploads from stdin, since it may
|
|
require data to be sent twice and then the client must be able to rewind. If
|
|
the need should arise when uploading from stdin, the upload operation fails.
|
|
|
|
Used together with --user.
