Revision 1221282

* Improve performance of parameter processing
      <add>
        Improve performance of parameter processing for GET and POST requests.
        Also add an option to limit the maximum number of parameters processed
        per request. This defaults to 10000. Excessive parameters are ignored.
        Note that <code>FailedRequestFilter</code> can be used to reject the
        request if some parameters were ignored. (markt/kkolinko)

      <add>
        New filter <code>FailedRequestFilter</code> that will reject a request
        if there were errors during HTTP parameter parsing. (kkolinko)
      </add>
