Question

我正在尝试强制从网站的www子域重定向到forum子域，同时保留查询字符串。换句话说，我希望如此：

http://www.website.com/index.php?key=value

转变为：

http://forum.website.com/index.php?key=value

所以我写了这个所谓的简单规则：

RewriteCond %{HTTP_HOST} ^www\.website\.com$
RewriteRule (.*) http://forum.website.com/$1 [L,QSA,R=301]

这是我在.htaccess中的唯一重写规则。

上面的示例网址被重写为：

http://forum.website.com/forum/index.php?key=value

这种奇怪的行为（以及对我来说，意外的）行为是什么？我做错了什么/错过了什么？

编辑2：这是我的website.conf：

<VirtualHost *:80>
    ServerName website.com

    DocumentRoot /var/www/website/forum/
</VirtualHost>

<VirtualHost *:80>
    ServerName www.website.com

    DocumentRoot /var/www/website/forum
</VirtualHost>

<VirtualHost *:80>
    ServerName forum.website.com

    DocumentRoot /var/www/website/forum
    <Directory />
         AddHandler fcgid-script .php
         FCGIWrapper /usr/lib/cgi-bin/php5 .php
         Options ExecCGI Indexes FollowSymLinks MultiViews
         AllowOverride All
         Order allow,deny
         allow from all
        </Directory>
</VirtualHost>

Answer 1

检查重写日志我发现forum/已经是网址的一部分。试试这个：

RewriteCond %{HTTP_HOST} ^www\.website\.com$
RewriteRule ^forum/(.*) http://forum.website.com/$1 [L,QSA,R=301]

mod_rewrite将子域名前置为查询字符串
