Can I add these rules "as-is" into my httpd.conf?

Here are all my rules with comments:

<Directory /home/*/public_html>
    # prevent directory browsing
    Options All -Indexes

    # prevent access to htaccess files anywhere on the site
    <Files .htaccess>
        order allow,deny
        deny from all
    </Files>

    # prevent DIRECT access to the /inc/ directory and its PHP files
    <Files ~ "\.inc$">
        order allow,deny
        deny f开发者_开发技巧rom all
    </Files>

    # custom error documents
    ErrorDocument 400 /error/400.html
    ErrorDocument 401 /error/401.html
    ErrorDocument 403 /error/403.html
    ErrorDocument 404 /error/404.html
    ErrorDocument 500 /error/500.html

    # security requirement of the rewrite engine
    Options +FollowSymLinks

    # turn on rewrite engine
    RewriteEngine On

    # remove PHP extension
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME}\.php -f
    RewriteRule ^(.*)$ $1.php
</Directory>

and

<Directory /home/*/public_html/images>
    # caching
    <IfModule mod_expires.c>
    ExpiresActive On

    <FilesMatch "\.(jpg|jpeg)$">
            ExpiresDefault "modification plus 1 year"
            Header set Cache-Control: "public, max-age=31536000"
            Header unset Last-Modified
        </FilesMatch>
    </IfModule>

    # turn on rewrite engine
    RewriteEngine On

    RewriteCond %{REQUEST_FILENAME} -s [OR]
    RewriteCond %{REQUEST_FILENAME} -l [OR]
    RewriteCond %{REQUEST_FILENAME} -d
    RewriteRule ^.*$ - [NC,L]

    # if file cannot be found
    RewriteRule ^.*$ /empty.jpg [NC,L]
</Directory>

Can I add these rules as they are to the bottom of my httpd.cnf? Or are there any mistakes? Or anything else I need to pay attention to? I don't want to screw anything up, even tho I'm just running my code on my localhost.

Any help would be appreciated. Thanks.

you can put them in httpd.cnf file! and they will work! The only thing you should pay attention is that to put them in right place(e.g in right site)
