title: htaccess codeigniter mod-rewrite, rewritecond to ignore subdirectory within main app directory
body: <p>I have an install of codeigniter up, running and all is good. Except I want to now offer my users a means of uploading images. The only place I could think to put the folder was in the applications directory (aptly renamed to "app" in my case). Anyway. Since its an MVC I need to run rewrite conditions all over the place. And I believe this to be one of the scenarios.</p>
  
  <p>What I need is to have a condition that works for this subfolder within the app folder</p>
  
  <p>my original rewrite condition is</p>
  
  <pre><code>RewriteCond $1 !^(index\.php|static|robots\.txt)
  </code></pre>
  
  <p>which works great for those but not for this one case so I need a new condition that works with the above but supports app/upload (is this even possible)?</p>
