1 Short: b 2 Long: cookie 3 Arg: <data|filename> 4 Protocols: HTTP 5 Help: Send cookies from string/file 6 Category: http 7 Example: -b cookiefile $URL 8 Example: -b cookiefile -c cookiefile $URL 9 Added: 4.9 10 --- 11 Pass the data to the HTTP server in the Cookie header. It is supposedly 12 the data previously received from the server in a "Set-Cookie:" line. The 13 data should be in the format "NAME1=VALUE1; NAME2=VALUE2". 14 15 If no '=' symbol is used in the argument, it is instead treated as a filename 16 to read previously stored cookie from. This option also activates the cookie 17 engine which will make curl record incoming cookies, which may be handy if 18 you are using this in combination with the --location option or do multiple URL 19 transfers on the same invoke. If the file name is exactly a minus ("-"), curl 20 will instead read the contents from stdin. 21 22 The file format of the file to read cookies from should be plain HTTP headers 23 (Set-Cookie style) or the Netscape/Mozilla cookie file format. 24 25 The file specified with --cookie is only used as input. No cookies will be 26 written to the file. To store cookies, use the --cookie-jar option. 27 28 If you use the Set-Cookie file format and do not specify a domain then the 29 cookie is not sent since the domain will never match. To address this, set a 30 domain in Set-Cookie line (doing that will include sub-domains) or preferably: 31 use the Netscape format. 32 33 This option can be used multiple times. 34 35 Users often want to both read cookies from a file and write updated cookies 36 back to a file, so using both --cookie and --cookie-jar in the same command 37 line is common. 38
