仅当存在查询字符串时，htaccess 301才重定向

Question

如果存在查询字符串，是否有可能将重定向(最好是301重定向)包含到外部域？

Example:
domain.com => domain.com
domain.com?query-string => another-domain.com?query-string

非常感谢!

@anubhava非常感谢您的帮助。现在，我要补充一些附加条件：

first-domain.com => https://www.first-domain.com
www.first-domain.com => https://www.first-domain.com
http://first-domain.com => https://www.first-domain.com

first-domain.com?query-string => https://www.another-domain.com/first-domain/?query-string
www.first-domain.com?query-string => https://www.another-domain.com/first-domain/?query-string
http://first-domain.com?query-string => https://www.another-domain.com/first-domain/?query-string
https://www.first-domain.com?query-string => https://www.another-domain.com/first-domain/?query-string

second-domain.com?query-string => https://www.another-domain.com/second-domain/?query-string
www.second-domain.com?query-string => https://www.another-domain.com/second-domain/?query-string
http://second-domain.com?query-string => https://www.another-domain.com/second-domain/?query-string
https://www.second-domain.com?query-string => https://www.another-domain.com/second-domain/?query-string

Answer 1

您可以在旧域的站点根.htaccess中使用此规则：

RewriteEngine On

RewriteCond %{QUERY_STRING} .
RewriteCond %{HTTP_HOST} !^another-domain\.com$ [NC]
RewriteCond %{HTTP_HOST} ^(?:www\.)?(.+)$ [NC]
RewriteRule ^ http://another-domain.com/%1%{REQUEST_URI} [L,NE,R=301]

• RewriteCond %{QUERY_STRING} .确保查询字符串存在。
• 查询字符串将自动转发到目标URL.

。
