cookie存储问题

[tooogooo]

请问cookie是不是只能存储一个信息？如下：
<script language="javascript">
<!--
function setCookie()
{
var the_name = prompt("What's your name?");
var the_cookie = escape(the_name);
document.cookie = the_cookie;
alert("Thanks, now go to the next page.");
}
function readCookie()
{
var the_cookie = document.cookie;
var broken_cookie = the_cookie.split(";");
var the_name = broken_cookie[0];
var the_name = unescape(the_name);
document.all.tt.value = the_name;
alert("Your name is: " + the_name);
}
-->
</script>
每次调用setCookie都把前面通过prompt输入的信息覆盖掉，我希望能同时存储多个信息，该怎么做呢？

var name1 = prompt("What's your name 1 ?");
var name2 = prompt("What's your name 2 ?");

document.cookie = "name1="+escape(name1);
document.cookie = "name2="+escape(name2);
或
document.cookie = "names="+escape(name1)+","+escape(name2);
