title: multiple nodejs apps for multiple domains on the same machine/ip. switching ports
body: <p>We have multiple domains each have embedded nodejs app we need to make every nodejs app running url like : <a href="http://domain_name:port_number" rel="nofollow">http://domain_name:port_number</a></p>
  
  <p>but we have a strange problem that every port we set for any nodejs app could be accessed from one domain not the domain we set the port in its nodejs app except 8080</p>
  
  <p>How to make all ports accessible from all domains running on the same machine/ip or open port number for a domain</p>
  
  <p>we use apache as the web server not using express or nginx</p>
