title: Making css image absolute paths goto the root of a sub directory, not the root of the main domain
body: <p>I have multiple sites for clients set up on a single development domain.  So the structure looks like this:</p>
  
  <p>developmentdomain.com/client1/site</p>
  
  <p>developmentdomain.com/client2/site
  developmentdomain.com/client/anothersite</p>
  
  <p>Every things works fine (including furls) if i have a base ref in the html and add a RewriteBase rule my htaccess file.</p>
  
  <p>But for some if within the css i have:</p>
  
  <pre><code>background: url("/assets/images/someImage.png");
  </code></pre>
  
  <p>Its trying to find the image at this location:
  developmentdomain.com/assets/images/someImage.png</p>
  
  <p>When it needs to be looking at:
  developmentdomain.com/client1/site/assets/images/someImage.png</p>
  
  <p>I'm guessing i need to do a rewrite rule in the htacess, but what?</p>
  
  <p>Oh and this is what i have in the htacces file for my RewriteBase</p>
  
  <pre><code>RewriteEngine On
  RewriteBase /client1/site
  </code></pre>
  
  <p>Any help much appreciated.</p>
  
  <p>Thanks
  Ben</p>
