Sends the "Referrer Page" information to the HTTP server. This can also be set
with the --header flag of course. When used with --location you can append
";auto" to the --referer URL to make curl automatically set the previous URL
when it follows a Location: header. The \&";auto" string can be used alone,
even if you do not set an initial --referer.

If this option is used several times, the last one will be used.
