code: public boolean pushResource(final String path, final HttpString method, final HeaderMap requestHeaders, HttpHandler handler) {
          return false;
      }
docs: Attempts to push a resource if this connection supports server push. Otherwise the request is ignored.
  
  Note that push is always done on a best effort basis, even if this method returns true it is possible that
  the remote endpoint will reset the stream.
  
  The {@link io.undertow.server.HttpHandler} passed in will be used to generate the pushed response
  
  
  @param path The path of the resource
  @param method The request method
  @param requestHeaders The request headers
  @return <code>true</code> if the server attempted the push, false otherwise
