Apache .htaccess 301重定向问题

我需要301从example.com重定向到www.example.com。这是可行的解决方案，但何时 我把它粘贴在整个网站上。htaccess网站关闭

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

htaccess文件

php_flag magic_quotes_gpc off
php_flag magic_quotes_runtime off
php_flag register_globals off

RewriteEngine On

RewriteRule ^.htaccess$ - [F]
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^(.*)$ $1 [L]
Options -Indexes
AddDefaultCharset windows-1251
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(service|news|search|project)/?$ index.php?menu=$1
RewriteRule ^error/([0-9]+)/?$ index.php?menu=error&loadinfo=$1
RewriteRule ^page/([0-9]+)/?$ index.php?menu=page&loadinfo=$1
RewriteRule ^news/([0-9]+)/?$ index.php?menu=news&loadinfo=$1
RewriteRule ^news/page-([0-9]+)/?$ index.php?menu=news&page=$1
RewriteRule ^service/([0-9]+)/?$ index.php?menu=service&category=$1
RewriteRule ^service/([0-9]+)/([0-9]+)/?$ index.php?menu=service&category=$1&loadinfo=$2
RewriteRule ^project/([0-9]+)/?$ index.php?menu=project&loadinfo=$1

您拥有.htaccess权限的文件夹的

AllowOverride

值是多少？您的

DocumentRoot

（或

VirtualHost

）规范需要设置为至少

AllowOverride选项

，以便允许.htaccess文件中的

php\u标志

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