      <dt>Proxying</dt>
      <dd>O novo m�dulo <code class="module"><a href="/mod/mod_proxy_balancer.html">mod_proxy_balancer</a></code> fornece
          servi�os de carregamento de balenceamento para <code class="module"><a href="/mod/mod_proxy.html">mod_proxy</a></code>. O novo m�dulo <code class="module"><a href="/mod/mod_proxy_ajp.html">mod_proxy_ajp</a></code> oferece suporte para o <code>Protocolo Apache JServ
          vers�o 1.3</code>, usado pelo <a href="http://tomcat.apache.org/">Apache Tomcat</a>.</dd>

      <dt>Filtragem Inteligente (Smart Filtering)</dt>
      <dd>O <code class="module"><a href="/mod/mod_filter.html">mod_filter</a></code> introduz configura��o din�mica para
          o filtro de sa�da de dados. Permitindo que os filtros sejam
      condicionalmente inseridos, baseando-se nos cabe�alhos <em>Request</em> ou <em>Response</em> ou em vari�veis do
      ambiente, ele acaba com os problemas de depend�ncias e pedidos
          da arquitetura 2.0.</dd>

      <dt><code class="module"><a href="/mod/mod_authnz_ldap.html">mod_authnz_ldap</a></code></dt>
      <dd>Este m�dulo � uma migra��o do <code>mod_auth_ldap</code>,
          da vers�o 2.0 para a estrutura 2.2 de <code>Authn/Authz</code>.
      As novas funcionalidades incluem o uso de atributos LDAP e

      <dt><code class="module"><a href="/mod/mod_info.html">mod_info</a></code></dt>
      <dd>Adicionado um novo argumento <code>?config</code> que
          mostra a configura��o das diretrizes analisadas pelo
      Apache, incluindo o nome do arquivo e o n�mero da linha.
      Esse m�dulo tamb�m mostra a ordem de todos os ganchos de
          pedidos (request hooks) e informa��es adicionais sobre

    <dl>
      <dt>API do APR 1.0</dt>

      <dd>O Apache 2.2 utiliza a API do APR 1.0. Todas as fun��es e
          s�mbolos antigos foram removidos do <code>APR</code> e
      <code>APR-Util</code>. Para mais detalhes, visite o
          <a href="http://apr.apache.org/">Website do APR</a>.</dd>

      <dt>Registros de Erros de Conex�o (logs)</dt>

      <dd>Uma nova fun��o <code>ap_log_cerror</code>, foi adicionada
          para registrar erros que ocorrem na conex�o do cliente.
      Quando documentado no di�rio de log, a mensagem inclui o
      endere�o IP do cliente.</dd>

      <dt>Adicionado Gancho de Teste de Configura��o</dt>

      <dd>Um novo gancho (hook), <code>test_config</code> foi
          adicionado para auxiliar m�dulos que querem executar
      c�digos especiais apenas quando o usu�rio passa o
      par�metro <code>-t</code> para o httpd.</dd>

      <dt>Ajustar o Stacksize dos "Threaded MPM's"</dt>

      <dd>Uma nova diretriz chamada <code>ThreadStackSize</code>,
          foi adicionada para ajustar o tamanho das stacks em todos
          os threadeds MPMs. Essa � uma pr�tica necess�rio para alguns
      m�dulos de terceiros em plataformas com tamanhos de stacks
      pequenos por padr�o.</dd>

      <dt>Negocia��o de Protocolo para filtros de sa�da</dt>

      <dd>No passado, todo filtro era respons�vel por garantir
          a gera��o de cabe�alhos de resposta correto que os afetava.
      Os filtros agora podem delegar o gerenciamento de protocolos
      comuns para <code class="module"><a href="/mod/mod_filter.html">mod_filter</a></code>, usando chamadas
      de <code>ap_register_output_filter_protocol</code> ou
          <code>ap_filter_protocol</code>.</dd>
