Send the 304 Not Modified response
```js import etag from "etag"; import { renderToString } from "react-dom/server"; import type { EntryContext, HandleDataRequestFunction } from "remix"; import { RemixServer } from "remix";
export default function handleRequest( request: Request, status: number, headers: Headers, remixContext: EntryContext ) { let markup = renderToString( <RemixServer context={remixContext} url={request.url} /> );
headers.set("Content-Type", "text/html"); headers.set("ETag", etag(markup));
// check if the
If-None-Matchheader matches the ETag if (request.headers.get("If-None-Match") === headers.get("ETag")) { // and send an empty Response with status 304 and the headers. return new Response("", { status: 304, headers }); }return new Response("<!DOCTYPE html>" + markup, { status, headers }); }
export let handleDataRequest: HandleDataRequestFunction = async ( response: Response, { request } ) => { let body = await response.text();
if (request.method.toLowerCase() === "get") { response.headers.set("etag", etag(body)); // As with document requests, check the
If-None-Matchheader // and compare it with the Etag, if they match, send the empty 304 Response if (request.headers.get("If-None-Match") === response.headers.get("ETag")) { return new Response("", { status: 304, headers: response.headers }); } }return response; }; ```
