mod_rewrite隐藏.php扩展名并删除其他标题

Question

I would like to hide php extension in url and in the responses of my Apache

I tried it with the following tipycal configuration:

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^(.*)$ $1.php [L,QSA]

DirectoryIndex index.php index.html

DocumentRoot /var/www/mysite
<Directory /var/www/mysite>
    Options -Indexes -MultiViews FollowSymLinks
    AllowOverride None
    Order allow,deny
    Allow from all
</Directory>
...

but I do not understand why Apache adds a set of headers that I think are unnecessary. for example about this url:

http://mysite/page

Edit: disabling Content Negotiation with -MultiViews cause:
