ASP Cookies
A cookie is a small piece of information that ASP stores on the visitor's own browser using Response.Cookies, and later reads back with Request.Cookies.
What Is a Cookie?
A cookie is a tiny text value that a web server asks a browser to hold onto. The browser stores it on the visitor's own computer and sends it back to the server with every later request to the same site. ASP uses cookies to remember small facts about a visitor, such as a chosen username or a display preference, between separate visits.
Writing a Cookie
<%
' Store the visitor's name in a cookie called "username"
Response.Cookies("username") = "Priya"
' Keep this cookie around for 30 days instead of just this browser session
Response.Cookies("username").Expires = DateAdd("d", 30, Now())

Dim strName
strName = Request.Cookies("username")
If strName = "" Then
Response.Write "Welcome, stranger!"
Else
Response.Write "Welcome back, " & strName & "!"
End If
%>Cookies With Multiple Values (Subkeys)
A single cookie can hold several related values, called subkeys, instead of you creating a separate cookie for every piece of data. This keeps related information bundled together under one cookie name.
Cookie Subkeys
<%
Response.Cookies("visitor")("name") = "Arjun"
Response.Cookies("visitor")("city") = "Pune"
Response.Cookies("visitor").Expires = DateAdd("m", 1, Now())
%>
<%
' On a later page:
Response.Write Request.Cookies("visitor")("name") & " from " & Request.Cookies("visitor")("city")
%>Exercise: ASP Cookies
