28  * Test aggregation of query string and POST parameters. According to
29  * Servlet 2.4 PFD, Section 4.1, all such parameters should be aggregated,
30  * and if there are duplicate parameter names from both sources, the
31  * parameter value(s) from the query string should appear first in the
32  * values returned by request.getParameterValues().
33  * <p>
34  * This test is the same as Aggregate01, except that it uses the new
35  * <code>getParameterMap()</code> method to retrieve parameter values.
