ASP Cookies

Cookies in ASP are used to store small pieces of data on the client-side, enabling persistent state management across multiple requests. ASP provides built-in methods to create, read, and delete cookies.

Key Topics

Creating Cookies

Example

<%
    Response.Cookies("user")("name") = "John Doe"
    Response.Cookies("user").Expires = DateAdd("d", 7, Now())
    Response.Write("Cookie has been set.")
%>

Explanation: This example creates a cookie named user with a property name and sets its expiration date to one week from the current time.

Reading Cookies

Example

<%
    If Request.Cookies("user")("name") <> "" Then
        Response.Write("Hello, " & Request.Cookies("user")("name") & "!")
    Else
        Response.Write("No cookie found.")
    End If
%>

Explanation: This example reads the value of a cookie and displays a personalized greeting if the cookie exists.

Deleting Cookies

Example

<%
    Response.Cookies("user").Expires = DateAdd("d", -1, Now())
    Response.Write("Cookie has been deleted.")
%>

Explanation: This example deletes a cookie by setting its expiration date to a past date.
