Dear members,

I really appreciate your time to look at my problem, I’m new to workers.

I created a worker to return a string as HTML.

Can Cloudflare cache html response from worker? I did not see it cache the HTML response
I have tried to add a response header “Cache-Control”

“`
export default {
async fetch(request, env, ctx) {

const url = new URL(request.url);
const html = `<!DOCTYPE html>
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
</head>
    <body>
      <h1>  ${url} ------> ${new Date().toLocaleString()}"</h1>
      <p>This markup was generated by a Cloudflare Worker.</p>
    </body>`;

return new Response(html, {
  headers: {
    "content-type": "text/html;charset=UTF-8",
    "Cache-Control": "public, max-age=300, s-maxage=600"
  },
});

}

};

“`
I also tried to create a cache rule for cache everything. I still did not see a catch header available in response.

My worker URLs:
https://whatfood-sow-worker.whatfood.workers.dev/
https://production.whatfood-sow-worker.whatfood.workers.dev/
https://sow.whatfood.work/

How to achieve cache HTML response?

Workers can use the Cache API to cache things, but they themselves cannot be cached. The Cache API will also only work on custom domains:
https://developers.cloudflare.com/workers/examples/cache-api/
https://developers.cloudflare.com/workers/runtime-apis/cache/

Documentation for Cloudflare Workers, a serverless execution environment that allows you to create entirely new applications or augment existing ones …

The Cache API allows fine grained control of reading and writing from the Cloudflare global network cache.

#

The Cache API is also only local cloudflare colo (location) cache, and does not support Tiered Caching or Cache Reserve, and of course your worker will always be invocated, even just to check and return a response from cache

Thank you so much and your time. I just started it yesterday. I am very impressed with the speed of the worker.
