<body>

<h4>The cookie name we're using for this sample is: <em><%= COOKIE_NAME %></em></h4>

<form action="cookies.aspx" method="post" runat="server">
<asp:Button type="submit" id="btnSetCookie" text="Set Cookie" OnClick="btnSetCookie_OnClick"
runat="server" />
<asp:Button type="submit" id="btnRemoveCookie" text="Remove Cookie"
OnClick="btnRemoveCookie_OnClick" runat="server" />

<p>
To see the cookie's current status you'll need to click below.  This is because the response
which adds or deletes the cookie happens after the request is already done.  As such, those changes aren't
available from the request collection until the next request.
