请问一个网站互不关联的不同页面如何获取同一cookie值？

比如说一个网站同一个目录下有几个互不关联的页面：1.php,2.php,3.php
一个用户访问1.php后生成cookie:

setcookie('mycookie1',$c1);
setcookie('mycookie2',$c2);
setcookie('mycookie3',$c3);

如果这个用户从别的网站点击超链接进入2.php,结果在2.php中不能读到1.php设置的cookie值。
如果我在1.php中做个超链接连到3.php，从1.php点超链接访问3.php，在3.php上就能显示出我在1.php设置的cookie值：
2.php和3.php的代码都一样：

$cc1 = $_COOKIE['mycookie1'];
$cc2 = $_COOKIE['mycookie2'];
$cc3 = $_COOKIE['mycookie3'];
echo $cc1;
echo $cc2;
echo $cc3;

请问怎样才能在跟1.php完全关联的3.php页面中读取到1.php设置的cookie值？
