+Short: b
+Long: cookie
+Arg: <name=data>
+Protocols: HTTP
+---
+Pass the data to the HTTP server in the Cookie header. It is supposedly
+the data previously received from the server in a "Set-Cookie:" line.  The
+data should be in the format "NAME1=VALUE1; NAME2=VALUE2".
+
+If no '=' symbol is used in the argument, it is instead treated as a filename
+to read previously stored cookie from. This option also activates the cookie
+engine which will make curl record incoming cookies, which may be handy if
+you're using this in combination with the --location option or do multiple URL
+transfers on the same invoke.
+
+The file format of the file to read cookies from should be plain HTTP headers
+(Set-Cookie style) or the Netscape/Mozilla cookie file format.
+
+The file specified with --cookie is only used as input. No cookies will be
+written to the file. To store cookies, use the --cookie-jar option.
+
+Exercise caution if you are using this option and multiple transfers may
+occur.  If you use the NAME1=VALUE1; format, or in a file use the Set-Cookie
+format and don't specify a domain, then the cookie is sent for any domain
+(even after redirects are followed) and cannot be modified by a server-set
+cookie. If the cookie engine is enabled and a server sets a cookie of the same
+name then both will be sent on a future transfer to that server, likely not
+what you intended.  To address these issues set a domain in Set-Cookie (doing
+that will include sub domains) or use the Netscape format.
+
+If this option is used several times, the last one will be used.
+
+Users very often want to both read cookies from a file and write updated
+cookies back to a file, so using both --cookie and --cookie-jar in the same
+command line is common.
