body: <p>Is it possible to reuse a listening TCP port in linux in different processes ?</p>
  
  <p>for eg : process A and process B are listening on server=INADDR_ANY and port=10000</p>
  
  <p>if its impossible then how the apache http server is able to listen to port #80  in different process.</p>
  
  <p>Thanks in advance</p>
