title: HAProxy reload issue in cygwin
body: <p>I have this problem with reloading the HAProxy using this command:</p>
  
  <pre><code>haproxy -D -f gateway.cfg -p /var/run/haproxy.pid -D -sf $(cat /var/run/haproxy.pid)
  </code></pre>
  
  <p>The error result </p>
  
  <pre><code>[ALERT] 169/001728 (3844) : Starting frontend proxy: cannot bind socket
  </code></pre>
  
  <p>I have tried adding user root or Administrator in the config but to no avail. The file permission according to ls -la is <code>Administrator none</code>. It makes me think HAProxy does not completely support windows and I wonder how does -sf/-st prefix work? (I tried in unix system and it turns out working correctly. The HAProxy config is shown below</p>
