Apache rewrite 出现 400 Bad Request 的解决方法

<VirtualHost *:80 *:81>    

    ServerAdmin [e-mail]    

    DocumentRoot /active/www/yingchao123/trade    

    ServerName trade.test.yingchao123.com

    ServerAlias trade.yingchao123.com

    

    RewriteEngine On

    RewriteRule ^([\da-z]{1,10})$ ./index.php?mod=list&do=unique&alias=$1 [L]    

    RewriteRule ^([\da-z]{1,10})&(.+)$ ./index.php?mod=list&do=unique&alias=$1&$2 [L]

</VirtualHost>
但这样写会出现 出现 400 Bad Request 错误

解决方法是将rewrite规则写倒directory中：

<VirtualHost *:80 *:81>    

    ServerAdmin [e-mail]    

    DocumentRoot /active/www/yingchao123/trade    

    ServerName trade.test.yingchao123.com

    ServerAlias trade.yingchao123.com

    <Directory "/active/www/yingchao123/trade">

        RewriteEngine On

        RewriteRule ^([\da-z]{1,10})$ ./index.php?mod=list&do=unique&alias=$1 [L]        

        RewriteRule ^([\da-z]{1,10})&(.+)$ ./index.php?mod=list&do=unique&alias=$1&$2 [L]

    </Directory>

</VirtualHost>
重启Apache，问题解决

 说明：apache检查配置是否语法错误httpd.exe -t 或者apachectl -t，nginx对应的命令是nginx -t
