Hi everyone,
I am trying to create a simple website using cookies to remember the last 2 links visited on my site. It is a very simple 2 column website:
<%@page contentType="text/html" pageEncoding="UTF-8" import="java.util.*"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Testing Site</title>
</head>
<body>
<table border="1" width="800" valign="top">
<tr>
<td width="300" valign="top">
<h2>Navigation</h2>
<%
if(request.getParameter("genre") == null) { %>
<p>Please select a music genre:</p>
<form action="index.jsp">
<input type="radio" name="genre" value="rock" /> Rock <br />
<input type="radio" name="genre" value="pop" /> Pop <br />
<input type="submit" value="Search" />

<% }
if (request.getParameter("genre") != null) {
if (request.getParameter("genre").equals("rock")) { %>
<p>You have chosen <%=request.getParameter("genre")%>. Here is a list of subgenres:</p>
<form action="index.jsp">

</form>
<%
}
if (request.getParameter("genre").equals("pop")) { %>
<p>You have chosen <%=request.getParameter("genre")%>. Here is a list of subgenres:</p>

</html>Right now, cookies have not been implemented. I am simply organizing the flow of the website.
Now my question is: How do I add cookies to make my website remember the last 2 or 3 links visited on the website? As you can see, I just entered Site One, Site Two, and Site Three for intuitive purposes and they are static.
I am not very familiar with implementing cookies, but I do understand how they work.
Thanks in advance!
