"Response.Cookies" amfani ne da su kafa cookie ko sanya kuma cookie na girma:

<%
Response.Cookies("firstname")="Alex"
%>

a cikin koda da tsakiyar abinci, a kafa cookie mai sunan "firstname" kuma a sanya masa kuma aleex .

koyi iya yin da cookie yin da ajiyarin, baiwa yin da ajiyarin wuri wanda zai aiki:

<%
Response.Cookies("firstname")="Alex"　
Response.Cookies("firstname").Expires=#May 10,2002#
%>

现在，名为 "firstname" 的 cookie 的值是 "Alex"，同时它在用户电脑中的失效日期是 2002 年 5 月 10 日。

"Request.Cookies" 命令用于取回 cookie 的值。

在下面的例子中，我们取回了 cookie "firstname" 的值，并把它显示到页面上：

<%
fname=Request.Cookies("firstname")
response.write("Firstname=" & fname)
%>

Output:

Firstname=Alex

一个 cookie 可以包含一个多值的集合。我们称之为 cookie 拥有 key 。

在下面的例子中，我们要创建一个名为 "user" 的 cookie 集合。"user" cookie 拥有包含有关用户信息的 key 。

<%
Response.Cookies("user")("firstname")="John"
Response.Cookies("user")("lastname")="Adams"
Response.Cookies("user")("country")="UK"
Response.Cookies("user")("age")="25"
%>

下面的代码可读出所有服务器已向用户发送的 cookie 。请注意，我们使用了 HasKeys 属性来判断 cookie 是否拥有 key ：

<html>
<body>
<%
dim x,y
for each x in Request.Cookies
  response.write("<p>")
  if Request.Cookies(x).HasKeys then
    for each y in Request.Cookies(x)
      response.write(x & ":" & y & "="　& Request.Cookies(x)(y))
      response.write("<br /")
    next
  kuma
    Arofin zai hukun "x & "=" & Request.Cookies(x) & "<br />"
  end if
  response.write "</p>"
next
%>
</body>
</html>
%>

Output:

firstname=Alex
user:firstname=John
user:lastname=Adams
user:
country=UK
user:
age=25
