      Use io.undertow.server.handlers.LocalNameResolvingHandler ('resolve-local-name' in expression-filter).
      However, it does have a performance penalty as it does a reverse DNS lookup.

      #CLI command

      /subsystem=undertow/configuration=filter/expression-filter=resolve-local-name-filter:add(expression=resolve-local-name)
/subsystem=undertow/server=default-server/host=default-host/filter-ref=resolve-local-name-filter:add()

      HttpServletRequest getLocalName() returns IP instead of hostname

      If I deploy the below sample code on EAP 7.x

      protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
          System.out.println(request.getLocalName());
          System.out.println(request.getClass());
}

      Output on EAP 7

      17:10:06,950 INFO  [stdout] (default task-1) 10.65.193.93
17:10:06,950 INFO  [stdout] (default task-1) class io.undertow.servlet.spec.HttpServletRequestImpl

      IP address instead of hostname
