Apache 访问控制允许源

不确定到底是什么问题-我在apache上有一个web应用程序，它的木偶主干模型连接到不同端口的服务器端。我在下面尝试允许访问，但没有看到效果：

这在httpd.conf的目录标记下

   <IfModule mod_headers.c>
         Header set Access-Control-Allow-Origin  "*"
    </IfModule>


Header module is loaded as ./apachectl -M results below

这没用。我的设置如下：标题集访问控制允许来源*标题集访问控制允许标题来源，X-request-With，内容类型，接受标题集访问控制允许凭据true，但错误相同。
