  25. .TH CURLOPT_COOKIE 3 "January 02, 2023" "libcurl 7.88.1" "curl_easy_setopt options"
  26. .SH NAME
  27. CURLOPT_COOKIE \- HTTP Cookie header
  28. .SH SYNOPSIS
  29. .nf
  30. #include <curl/curl.h>
  31. CURLcode curl_easy_setopt(CURL *handle, CURLOPT_COOKIE, char *cookie);
  32. .fi
  33. .SH DESCRIPTION
  34. Pass a pointer to a null-terminated string as parameter. It will be used to
  35. set a cookie in the HTTP request. The format of the string should be
  36. NAME=CONTENTS, where NAME is the cookie name and CONTENTS is what the cookie
  37. should contain.
  38. If you need to set multiple cookies, set them all using a single option
  39. concatenated like this: "name1=content1; name2=content2;" etc.
  40. This option sets the cookie header explicitly in the outgoing request(s). If
  41. multiple requests are done due to authentication, followed redirections or
  42. similar, they will all get this cookie passed on.
  43. The cookies set by this option are separate from the internal cookie storage
  44. held by the cookie engine and will not be modified by it. If you enable the
  45. cookie engine and either you have imported a cookie of the same name (e.g. 'foo')
  46. or the server has set one, it will have no effect on the cookies you set here.
  47. A request to the server will send both the 'foo' held by the cookie engine and
  48. the 'foo' held by this option. To set a cookie that is instead held by the
  49. cookie engine and can be modified by the server use
  50. \fICURLOPT_COOKIELIST(3)\fP.
  51. Using this option multiple times will only make the latest string override the
  52. previous ones.
  53. This option will not enable the cookie engine. Use \fICURLOPT_COOKIEFILE(3)\fP
  54. or \fICURLOPT_COOKIEJAR(3)\fP to enable parsing and sending cookies
  55. automatically.
  56. The application does not have to keep the string around after setting this
  57. option.
  58. .SH DEFAULT
  59. NULL, no cookies
  60. .SH PROTOCOLS
  61. HTTP
  62. .SH EXAMPLE
  63. .nf

  68. curl_easy_perform(curl);
  69. }

  72. If HTTP is enabled
  73. .SH RETURN VALUE
  74. Returns CURLE_OK if HTTP is enabled, CURLE_UNKNOWN_OPTION if not, or
  75. CURLE_OUT_OF_MEMORY if there was insufficient heap space.
