如何通过htaccess阻止X以外的所有域对wp-admin目录的访问

Question

我有一个wordpress多站点，并且我们有一个生产线开发人员。我试图禁止从除my-beta-site.com以外的所有其他域对wp-login.php和wp-admin目录的所有访问。我在使用wordpress中的自定义404页面时无法解决此问题。我感觉到我在.htaccess中的订单导致此问题，并且我可能未正确应用重写规则。我花了很多时间来使它与https重定向一起很好地工作（这导致403与404无限循环）。我当前的解决方案正在运行，但是即使与指定的域不匹配，它也会破坏wp-admin目录中的自定义404页面。我想解决这个问题。

当前代码违反了自定义404

    RewriteEngine On
    RewriteBase /

    RewriteCond %{REQUEST_URI} !\.well-known/acme-challenge

    RewriteCond %{HTTPS} !=on
    RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

    # if it is not for domain gapbeta.org then block it
    RewriteCond %{HTTP_HOST} !^(.*)?my-beta-site\.com [NC]
    RewriteCond %{REQUEST_URI} ^(.*)?wp-login\.php(.*)$ [OR]
    RewriteCond %{REQUEST_URI} ^(.*)?wp-admin/(.*)?$
    RewriteRule . - [R=404]

    RewriteRule ^index\.php$ - [L]

    # add a trailing slash to /wp-admin
    RewriteRule ^wp-admin$ wp-admin/ [R=301,L]
    RewriteCond %{REQUEST_FILENAME} -f [OR]
    RewriteCond %{REQUEST_FILENAME} -d
    RewriteRule ^ - [L]
    RewriteRule ^(wp-(content|admin|includes).*) $1 [L]
    RewriteRule ^(.*\.php)$ $1 [L]

    RewriteRule . index.php [L]

原始htaccess，无需添加

    RewriteEngine On
    RewriteBase /

    RewriteCond %{REQUEST_URI} !\.well-known/acme-challenge

    RewriteCond %{HTTPS} !=on
    RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

    RewriteRule ^index\.php$ - [L]

    # add a trailing slash to /wp-admin
    RewriteRule ^wp-admin$ wp-admin/ [R=301,L]
    RewriteCond %{REQUEST_FILENAME} -f [OR]
    RewriteCond %{REQUEST_FILENAME} -d
    RewriteRule ^ - [L]
    RewriteRule ^(wp-(content|admin|includes).*) $1 [L]
    RewriteRule ^(.*\.php)$ $1 [L]

    RewriteRule . index.php [L]
