.htaccess从子域重定向到www

Question

我在我们的beta测试中使用了一个子域beta.domain.co。我现在希望将beta.domain.co重定向到www.domain.co及其所有路线。

我测试过，但我没有看到任何变化。

RewriteCond %{HTTP_HOST} beta.domain.com$ [NC] 
RewriteRule ^(.*)$ http://www.domain.com/$1 [L,R=301] 

它是正确的吗？

这里完整的.htaccess（最后3行是我加的是重定向）：

<IfModule mod_rewrite.c> 
    RewriteEngine On 

    # Determine the RewriteBase automatically and set it as environment variable. 
    # If you are using Apache aliases to do mass virtual hosting or installed the 
    # project in a subdirectory, the base path will be prepended to allow proper 
    # resolution of the app.php file and to redirect to the correct URI. It will 
    # work in environments without path prefix as well, providing a safe, one-size 
    # fits all solution. But as you do not need it in this case, you can comment 
    # the following 2 lines to eliminate the overhead. 
    RewriteCond %{REQUEST_URI}::$1 ^(/.+)/(.*)::\2$ 
    RewriteRule ^(.*) - [E=BASE:%1] 

    # Sets the HTTP_AUTHORIZATION header removed by apache 
    RewriteCond %{HTTP:Authorization} . 
    RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}] 

    # Redirect to URI without front controller to prevent duplicate content 
    # (with and without `/app.php`). Only do this redirect on the initial 
    # rewrite by Apache and not on subsequent cycles. Otherwise we would get an 
    # endless redirect loop (request -> rewrite to front controller -> 
    # redirect -> request -> ...). 
    # So in case you get a "too many redirects" error or you always get redirected 
    # to the start page because your Apache does not expose the REDIRECT_STATUS 
    # environment variable, you have 2 choices: 
    # - disable this feature by commenting the following 2 lines or 
    # - use Apache >= 2.3.9 and replace all L flags by END flags and remove the 
    # following RewriteCond (best solution) 
    RewriteCond %{ENV:REDIRECT_STATUS} ^$ 
    RewriteRule ^app\.php(/(.*)|$) %{ENV:BASE}/$2 [R=301,L] 

    # If the requested filename exists, simply serve it. 
    # We only want to let Apache serve files and not directories. 
    RewriteCond %{REQUEST_FILENAME} -f 
    RewriteRule .? - [L] 

    # Rewrite all other queries to the front controller. 
    RewriteRule .? %{ENV:BASE}/app.php [L] 

    # REDIRECTION FROM OLD SUBDOMAIN TO NEW DOMAIN 
    RewriteCond %{HTTP_HOST beta.domain.co$ [NC] 
    RewriteRule ^(.*)$ http://www.domain.co/$1 [L,R=301] 

</IfModule>

是的，你的规则是正确的，但它被忽略。你需要把它放在你的.htaccess中的其他规则之前：

RewriteEngine on 
RewriteCond %{HTTP_HOST} beta.domain.com$ [NC] 
RewriteRule ^(.*)$ http://www.domain.com/$1 [L,R=301]
