Specify to which file you want curl to write all cookies after a completed
operation. Curl writes all cookies from its in-memory cookie storage to the
given file at the end of operations. If no cookies are known, no data is
written. The file is created using the Netscape cookie file format. If you set
the file name to a single dash, "-", the cookies are written to stdout.
The file specified with --cookie-jar is only used for output. No cookies are
read from the file. To read cookies, use the --cookie option. Both options
can specify the same file.
This command line option activates the cookie engine that makes curl record
and use cookies. The --cookie option also activates it.
If the cookie jar cannot be created or written to, the whole curl operation
does not fail or even report an error clearly. Using --verbose gets a warning
displayed, but that is the only visible feedback you get about this possibly
lethal situation.
