Ubuntu Manpage: CURLOPT_COOKIE - HTTP Cookie header

NAME

       CURLOPT_COOKIE - HTTP Cookie header

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_COOKIE, char *cookie);

DESCRIPTION

Pass a pointer to a null-terminated string as parameter. It will be used to set a cookie
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.

If you need 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 will 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 will 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
will have no effect on the cookies you set here. A request to the server will send 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
CURLOPT_COOKIELIST(3).

Using this option multiple times will only make the latest string override the previous
ones.

This option will not enable the cookie engine. Use CURLOPT_COOKIEFILE(3) or
CURLOPT_COOKIEJAR(3) to enable parsing and sending cookies automatically.

The application does not have to keep the string around after setting this option.

DEFAULT

       NULL, no cookies
