我修改了我的htaccess文件，但不确定它是否正确

Question

我想在我的域名前面添加“www”，我已经完成但不确定它是否已正确添加，因为我从开源附带的原始.htaccess文件中删除了一些代码脚本。

原始.htaccess文件：

# secure htaccess file
<Files .htaccess>
 order allow,deny
 deny from all
</Files>

# disable directory browsing
Options All -Indexes

# disabel access to logs/template files
<Files ~ "\.(log|tpl)$">
 order allow,deny
 deny from all
</files>

RewriteEngine On
RewriteCond %{REQUEST_URI} ^/uploaded [NC]
RewriteCond %{REQUEST_URI} !\.(jpe?g|png|gif)$ [NC]
RewriteRule .* - [F,L]

当前.htaccess文件：

# secures htaccess file
<Files .htaccess>
 order allow,deny
 deny from all
</Files>

# disable directory browsing
Options All -Indexes

# disable access to logs/template files
<Files ~ "\.(log|tpl)$">
 order allow,deny
 deny from all
</files>

# Force www:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^websitename.com$ [NC]
RewriteRule ^(.*)$ http://www.websitename.com/$1 [L,R=301,NC]
RewriteEngine On
RewriteCond %{REQUEST_URI} ^/uploaded [NC]
RewriteCond %{REQUEST_URI} !\.(jpe?g|png|gif)$ [NC]
RewriteRule .* - [F,L]
