title: RewriteEngine On mandatory for all rewrites?
body: <p>I was just wondering if it would be necessary to include the RewriteEngine On and Rewrite Base / each time I add a rewrite? For example I would like to use both the "Removes the QUERY_STRING from the URL ^" and "block access to files during certain hours of the day ^" (Examples quoted from askapache.com)</p>
  
  <p>Removes the QUERY_STRING from the URL</p>
  
  <pre><code>RewriteEngine On
  RewriteBase /
  RewriteCond %{QUERY_STRING} .
  RewriteRule ^login.php /login.php? [L]
  </code></pre>
  
  <p>block access to files during certain hours of the day ^</p>
  
  <pre><code>Options +FollowSymLinks
  RewriteEngine On
  RewriteBase /
  # If the hour is 16 (4 PM) Then deny all access
  RewriteCond %{TIME_HOUR} ^16$
  RewriteRule ^.*$ - [F,L]
  </code></pre>
  
  <p>Can I possibly combine them into the following?</p>
  
  <pre><code>Options +FollowSymLinks
  RewriteEngine On
  RewriteBase /
  RewriteCond %{QUERY_STRING} .
  RewriteRule ^login.php /login.php? [L]
  # If the hour is 16 (4 PM) Then deny all access
  RewriteCond %{TIME_HOUR} ^16$
  RewriteRule ^.*$ - [F,L]
  </code></pre>
  
  <p>Thanks in advance for your time.</p>
