title: Custom Jetty Filters in Dropwizard
body: <p>I'm attempting to add a custom header filter in my Dropwizard instance to check to see if the request's version is synced to the Dropwizard instance's version.</p>
  
  <p>I see you can use <code>FilterBuilder</code> to add jetty <code>CrossOriginFilters</code>.  However, I am having trouble figuring out how to set a custom filter.</p>
  
  <p>Thanks</p>
