It is used to set one or more cookies in the HTTP request. The format of the string should be NAME=CONTENTS, where NAME is the cookie name and CONTENTS is what the cookie should contain. To set multiple cookies, set them all using a single option concatenated like this: "name1=content1; name2=content2;" etc. This option sets the cookie header explicitly in the outgoing request(s). If multiple requests are done due to authentication, followed redirections or similar, they all get this cookie passed on. The cookies set by this option are separate from the internal cookie storage held by the cookie engine and they are not be modified by it. If you enable the cookie engine and either you have imported a cookie of the same name (e.g. 'foo') or the server has set one, it has no effect on the cookies you set here. A request to the server sends both the 'foo' held by the cookie engine and the 'foo' held by this option. To set a cookie that is instead held by the cookie engine and can be modified by the server use \fICURLOPT_COOKIELIST(3)\fP. Using this option multiple times makes the last set string override the previous ones. This option does not enable the cookie engine. Use \fICURLOPT_COOKIEFILE(3)\fP or \fICURLOPT_COOKIEJAR(3)\fP to enable parsing and sending cookies automatically. The application does not have to keep the string around after setting this option. .SH DEFAULT NULL, no cookies .SH PROTOCOLS HTTP .SH EXAMPLE .nf int main(void) { CURL *curl = curl_easy_init(); if(curl) { curl_easy_setopt(curl, CURLOPT_URL, "https://example.com"); curl_easy_setopt(curl, CURLOPT_COOKIE, "tool=curl; fun=yes;"); curl_easy_perform(curl); } } .fi .SH AVAILABILITY If HTTP is enabled .SH RETURN VALUE Returns CURLE_OK if HTTP is enabled, CURLE_UNKNOWN_OPTION if not, or CURLE_OUT_OF_MEMORY if there was insufficient heap space. .SH "SEE ALSO" .BR CURLINFO_COOKIELIST (3), .BR CURLOPT_COOKIEFILE (3), .BR CURLOPT_COOKIEJAR (3), .BR CURLOPT_COOKIELIST (3), .BR CURLOPT_HTTPHEADER (3)
