Because it's a POST request, and getQueryString() doesn't return name/value
pairs from the POST body. getParameterNames() appears to consolidate both
actual query string pairs with any more found in the body. It seemed like
the easy way to go, but I've never seen a method return something where you
had to check the instanceof to know how to operate on it.
