As you render the page you may want to add additional headers. The HttpHeader component will do that for you. You can pass it a name and value and that will get added to the Response headers sent back to the browser.

Keep in mind, when streaming responses(renderStream), HTTP headers can only be included that are added before the stream first flushed. Be sure to add deferStream to any resources or createServerData$ calls that needed to be loaded before responding.
