Examples

"Response.Cookies" command is used to create a cookie or set cookie values:

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

In the above code, we have created a directory named "firstname" the cookie, and assign it to "Alex".

You can also set the properties for the cookie, for example, you set the cookie expire:

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

Now, the value named "firstname" of the cookie is "Alex", while its expiration date in the user's computer is May 10, 2002.

"Request.Cookies" command is used to retrieve a cookie value.

In the following example, we retrieve the cookie "firstname" value, and displays it on the page:

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

Output:
Firstname=Alex

A cookie can contain more than one set of values. We have called cookie key.

In the following example, we want to create a cookie collection named "user" of. "User" cookie has contains information about the user's key:

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

The following code can be read cookie has been sent by the user for all servers. Note that we use HasKeys property to determine whether the cookie has 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
else
Response.Write(x & "=" & Request.Cookies(x) & "<br>")
end if
response.write "</p>"
next
%>

</body>
</html>
%>

Output:

firstname=Alex

user:firstname=John
user:lastname=Smith
user:
country=Norway
user:
age=25
