title: .htaccess RewriteCond – adding multiple exceptions
body: <p>My question is very simple, but I want to get it absolutely right the first try, because I'm working on a live website and bad things could happen if I blew this :)</p>
  
  <p>So, as a part of a RewriteRule that forwards all my regular visitors to /myfolder/, there is an important line preventing the rule from being applied if you're already in that folder:</p>
  
  <pre><code>RewriteCond %{REQUEST_URI} !^/myfolder/
  </code></pre>
  
  <p>That works fine. What I want is to add my dev folder to that exception, so myself and my clients can access my development projects while all other URI's still get forwarded to /myfolder/</p>
  
  <p>I'm guessing I need to modify the RewriteCond along the lines of:</p>
  
  <pre><code>RewriteCond %{REQUEST_URI} !^/myfolder/ 
  </code></pre>
  
  <p>(here I basically need 'OR' in the right syntax) !^/dev/</p>
  
  <p>What's the correct syntax for this?</p>
