title: Is it possible to disable symfony's cache per request
body: <p>If a certain condition is met, is it possible to tell symfony not to cache the current request? I'm aware of the <code>contextual</code> configuration flag, but this is an action, and not a partial or component, so I don't think it applies.</p>
  
  <p><strong>Context:</strong> I'm running a multi-site CMS. Each site can have multiple domain names associated with it, but one is set as the primary. It a page request is made with the alternate domain name, it gets forwarded to the primary. But the action gets cached so when the same url is accessed, it serves the cache file instead of redirecting.</p>
