为什么 url 中缺少尾部斜杠会添加 :8080 来重定向？

Question

我在 Ubuntu/Apache 服务器上有两个网站。 一个在目录中

/var/www/html/dir1

并在 apache 中配置为虚拟服务器，并激活了 FollowSymlink 选项。回复

http://example.com

第二个是网页index.html中的

/var/www/html/dir2

获取将第二页链接到url的简单方法

http://example.com/dir2 

我在 /var/www/html/dir1 中创建了一个指向名为 dir1 的 /var/www/html/dir2 的软链接，一切正常。 参观

http://example.com/dir2/

在/var/www/html/dir2中引导到页面index.html。

到目前为止一切顺利。

虽然，访问

http://example.com/dir2

（注意缺少斜杠） 导致重定向到

http://example.com:8080/dir2/

为什么在这种情况下会添加端口？我怎样才能轻松删除它？

编辑：我需要删除端口，因为从 index.html 发出了一些 post 请求，并且 :8080 部分给我带来了一些 cors 问题。

编辑：虚拟主机配置

<VirtualHost *:8080>
    DocumentRoot "/var/www/dir1/drupal"
    ErrorLog /var/log/apache2/dir1-error.log
    CustomLog /var/log/apache2/dir1-access.log combined
    <Directory "/var/www/dir1/drupal/">

        AllowOverride all

在RewriteEngine On 行下方添加此规则：

# add a trailing slash to directories
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule [^/]$ %{REQUEST_URI}/ [L,NE,R=301]

并在新浏览器中重新测试或完全清除浏览器缓存。
