我subdomain.example.com重定向到www.subdomain.example.com.
訪問代碼：
# ensure www.
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^ https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
# ensure https
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteCond %{HTTPS} off
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
### END WWW & HTTPS
我在尋找
example.com到www.example.com
anything.example.com到anything.example.com
我怎樣才能解決這個問題？
更新：我為子域和根域使用一個 htaccess 檔案，出于某種原因，我不能為不同的域使用單獨的 htaccess 檔案。
注意：請不要將此問題標記為重復。我已經搜索了 stackoverflow 的其他部分，但沒有找到可行的解決方案。

您需要限制重寫條件以僅匹配頂級域：
# ensure www. to top level domain only
RewriteCond %{HTTP_HOST} ^[\w-] \.(com|net|in|co\.uk)$ [NC]
RewriteRule ^ https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
# ensure https
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteCond %{HTTPS} off
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
### END WWW & HTTPS
確保在測驗前清除瀏覽器快取。

# remove www if subdomain
RewriteCond %{HTTP_HOST} ^www\.([^.] \.[^.] \.[^.] )$ [NC]
RewriteRule ^ https://%1%{REQUEST_URI} [R=301,L]
# ensure https
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteCond %{HTTPS} off
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

# ensure https
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteCond %{HTTPS} off
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
