Not quite.

There are actually two aspects of cookies:

  1. Storing information server-side:

     On HTTP request, create a server-side session with a session ID (using,
     and store all information server-side until the session expires.
     The information stored server-side is NOT called “cookie(s)”;
     see e.g. <https://php.net/setcookie> and cf.
     <https://www.php.net/manual/en/intro.session.php>.

  2. Storing information client-side:

     a) For a server-side session, store the session ID in a cookie
        client-side, by sending a HTTP response message containing a
        “Set-Cookie” header field.  On every suitable HTTP request,
        the client includes the session ID in the “Cookie” header field of
        the HTTP request message.

<https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Set-Cookie>
<https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cookie>

     b) For a client-side (usually browser) session or for temporary storage
        that survives the end of a client-side session (given by the
        “expires“ value), store all the data in cookies client-side.  The
        client will transfer all relevant cookies to the server as described
        in a), but the data can also be exclusively used client-side.

Cookies can be read and set using the “document.cookie” property, unless 
they had been set with the “httponly” flag set.
