title: Can I install WebSocket Support in IIS in Production without downtime?
body: <p>We didn't realize we were missing support for WebSockets in IIS in our production environment due to the Windows feature not being installed (Windows Server 2012).</p>
  
  <p>Can we install the feature in our production environment without causing down time or the app pool on our web applications to recycle? What experience has anyone had installing features in Windows in production in general? Is there documentation somewhere that details what is safe or unsafe to do?</p>
