title: Is running multiple web: processes possible?
body: <p>Our PHP application runs on apache, however php-pm can be used make the application persistent (no warmup, database connection remains open, caches are populated and application initialized).</p>
  
  <p>I'd like to keep this behaviour when deploying to heroku, that is have apache serve static content and php-pm server the API layer. Locally this is handled using an <code>.htaccess</code> Rewrite proxy rule that sends all traffic from <code>/middleware</code> to php-pm listing on e.g. port <code>8082</code>.</p>
  
  <p>On heroku it would mean running two processes in the web dyno. Is that possible? </p>
  
  <p>If not- are there other alternatives that can be used to handle web traffic through different processes or make a persistent process listen to web traffic?</p>
