子域名无法在Firefox中打开

Question

无法使用localhost子域ex： abc.localhost 运行我的应用程序。它在Chrome中运行良好，但在Firefox / IE中无效

这是我的vhost条目的样子。我也尝试了ServerAlias名称，但似乎没有任何工作。任何线索都将受到高度赞赏。

    <VirtualHost *:80>
   # The name to respond to
   ServerName abc.localhost
   # Folder where the files live
   DocumentRoot "<PATH">
   # A few helpful settings...
   <Directory "<PATH>"
           Options -Indexes
   </Directory>
   <IfModule mod_headers.c>
Header add Access-Control-Allow-Origin %{AccessControlAllowOrigin}e env=AccessControlAllowOrigin
Header set Access-Control-Allow-Credentials true
  </IfModule>
