title: How do I handle ValidateAntiForgeryToken across linux servers
body: <p>I have deployed an asp.net core app on some load balanced linux servers. I getting an error when POSTing a form to a route due to a failing <code>ValidateAntiForgeryToken</code> attribute (if a POST does not go back to the same machine as the one that generated my form).</p>
  
  <p>With Windows and .Net classic I know to match <code>MachineKey</code> attributes in my <code>web.config</code> or <code>machine.config</code> files. </p>
  
  <p>So, how do I achieve the same on linux hosts and allow a token from one server to be validated on another?</p>
