This rule logs an issue whenever form fields and cookie values are accessed.
== Noncompliant Code Example
----
public void doPost(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException {
Cookie [] cookies = request.getCookies(); // Noncompliant
String hiddenValue = request.getParameter("hiddenField"); // Noncompliant
Map<String,String[]> params = request.getParameterMap(); // Noncompliant
String [] hiddenFieldValues = reqeust.getParameterValues("hiddenArray"); // Noncompliant
