title: Apache ProxyPass only for subdomain and folder
body: <p>I want to use ProxyPass and only apply for the following subdomain and folder:</p>
  
  <p>de.domain.com/blog/ -> <a href="http://blog.olddomain.com/de/" rel="nofollow noreferrer">http://blog.olddomain.com/de/</a></p>
  
  <p>Our new page will have multiple subdomains (each per locale). When i only use this:</p>
  
  <pre><code>ProxyPass /blog/ http://blog.olddomain.com/de/
  ProxyPassReverse /blog/ http://blog.olddomain.com/de/
  </code></pre>
  
  <p>All subdomains are using the rule. So my question is, how can i tell ProxyPass only apply this on <code>de.domain.com/blog/</code> and not on <code>en.domain.com/blog/</code> etc.</p>
  
  <p>Thank you!</p>
