  23. .TH CURLOPT_COOKIE 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
  24. .SH NAME
  25. CURLOPT_COOKIE \- HTTP Cookie header
  26. .SH SYNOPSIS
  27. .nf
  28. #include <curl/curl.h>
  29. CURLcode curl_easy_setopt(CURL *handle, CURLOPT_COOKIE, char *cookie);
  30. .fi
  31. .SH DESCRIPTION
  32. Pass a pointer to a null-terminated string as parameter. It will be used to
  33. set a cookie in the HTTP request. The format of the string should be
  34. NAME=CONTENTS, where NAME is the cookie name and CONTENTS is what the cookie
  35. should contain.
  36. If you need to set multiple cookies, set them all using a single option
  37. concatenated like this: "name1=content1; name2=content2;" etc.
  38. This option sets the cookie header explicitly in the outgoing request(s). If
  39. multiple requests are done due to authentication, followed redirections or
  40. similar, they will all get this cookie passed on.
  41. The cookies set by this option are separate from the internal cookie storage
  42. held by the cookie engine and will not be modified by it. If you enable the
  43. cookie engine and either you have imported a cookie of the same name (e.g. 'foo')
  44. or the server has set one, it will have no effect on the cookies you set here.
  45. A request to the server will send both the 'foo' held by the cookie engine and
  46. the 'foo' held by this option. To set a cookie that is instead held by the
  47. cookie engine and can be modified by the server use
  48. \fICURLOPT_COOKIELIST(3)\fP.
  49. Using this option multiple times will only make the latest string override the
  50. previous ones.
  51. This option will not enable the cookie engine. Use \fICURLOPT_COOKIEFILE(3)\fP
  52. or \fICURLOPT_COOKIEJAR(3)\fP to enable parsing and sending cookies
  53. automatically.
  54. The application does not have to keep the string around after setting this
  55. option.
  56. .SH DEFAULT
  57. NULL, no cookies
  58. .SH PROTOCOLS
  59. HTTP
  60. .SH EXAMPLE
