我正在使用 HTML 5 Boilerplate HTAccess 文件，并在其中使用选项 2（强制 www.）。我现在正在尝试删除文件扩展名（即 services.php 显示为服务），以下工作正常：
<IfModule mod_rewrite>
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.php -f
RewriteRule ^(.*)$ $1.php
</IfModule>
<IfModule mod_rewrite.c>
RewriteCond %{HTTPS} !=on
RewriteCond %{HTTP_HOST} !^www\..+$ [NC]
RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
</IfModule>
但是一旦与完整的 HTMl5 样板 .htaccess 文件结合使用，文件扩展名就不能正常工作（即，输入 /services 会给出 404，而不是屏蔽为 services.php）。不过万维网。工作正常。完整代码如下：
# Apache configuration file
# httpd.apache.org/docs/2.2/mod/quickreference.html
# Note .htaccess files are an overhead, this logic should be in your Apache config if possible
# httpd.apache.org/docs/2.2/howto/htaccess.html
# Techniques in here adapted from all over, including:
# Kroc Camen: camendesign.com/.htaccess
# perishablepress.com/press/2006/01/10/stupid-htaccess-tricks/
# Sample .htaccess file of CMS MODx: modxcms.com

### If you run a webserver other than Apache, consider:
