儘管配置正確，NamedVirtiaulHosts仍然無法工作

Question

Ubuntu 14.04服務器，Apache2。我在domain.tld下有一個Prestashop網店，工作正常。 我現在想在我的服務上安裝webmail，所以我添加了一個指向/ var/www/webmail的虛擬主機。

但是，當我去webmail.domain.tld，我總是得到重定向到domain.tld。

我已經谷歌了很多，它看起來不錯。這是DUMP_VHOSTS

root@ubuntu-1404:/etc/apache2# apachectl -t -D DUMP_VHOSTS 
VirtualHost configuration: 
*:443     is a NameVirtualHost 
     default server www.domain.tld (/etc/apache2/sites-enabled/domain.tld.conf:1) 
     port 443 namevhost www.domain.tld (/etc/apache2/sites-enabled/domain.tld.conf:1) 
       alias www.domain.tld 
       alias domain.tld 
     port 443 namevhost webmail.domain.tld (/etc/apache2/sites-enabled/webmail.domain.tld.conf:1) 
       alias webmail.domain.tld 
*:80     is a NameVirtualHost 
     default server www.domain.tld (/etc/apache2/sites-enabled/domain.tld.conf:48) 
     port 80 namevhost www.domain.tld (/etc/apache2/sites-enabled/domain.tld.conf:48) 
       alias www.domain.tld 
       alias domain.tld 
     port 80 namevhost webmail.domain.tld (/etc/apache2/sites-enabled/webmail.domain.tld.conf:39) 
       alias webmail.domain.tld 

輸出我還添加了webmail.domain.tld到我的主機文件（127.0.0.1），當我測試使用telnet 80，它也不起作用。

我發現很多帖子說我必須添加NamedVirtualHost：80，但似乎不贊成，因爲我然後得到一個錯誤，該命令不再起作用。 我也檢查了httpd.conf的REWRITES，但找不到一個。我也嘗試刪除「domain.tld」作爲默認網站的別名，但這也沒有任何區別。

相關的配置（2個conf文件）：

<VirtualHost *:443> 
    # The ServerName directive sets the request scheme, hostname and port that 
    # the server uses to identify itself. This is used when creating 
    # redirection URLs. In the context of virtual hosts, the ServerName 
    # specifies what hostname must appear in the request's Host: header to 
    # match this virtual host. For the default virtual host (this file) this 
    # value is not decisive as it is used as a last resort host regardless. 
    # However, you must set it for any further virtual host explicitly.

請闡明這光。

最後竟然是緩存。 FireFox緩存重定向，當我在InPrivate Chrome/Firefox中測試時，它按預期工作。
