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've 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
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_COOKIEJAR to enable parsing and sending cookies
