That's correct. Pages is full-domain.

Mozzy•10/31/24, 9:37 PM

I know it's helpful, but I would like the option to have stricter cache rules

M

Mozzy•10/31/24, 9:37 PM

Maybe a rewrite middleware before the caching?

SSpunkie :weicry:

I

Isaac McFadyen•10/31/24, 9:37 PM

You could write a Pages Function to proxy some routes to another backend but that would increase latency and always bill you for Function invocations.

MMozzy Maybe a rewrite middleware before the caching?

I

Isaac McFadyen•10/31/24, 9:37 PM

Oh I might have misunderstood. You want to disable that so it still hits the cache?

M

Mozzy•10/31/24, 9:37 PM

Exactly

I

Isaac McFadyen•10/31/24, 9:37 PM

If so there's a setting you can change in the Cloudflare dashboard.

Isaac McFadyen•10/31/24, 9:37 PM

Sec.

Try that

I

Isaac McFadyen•10/31/24, 9:38 PM

Then change Caching Level to "Ignore Query String"

I

Isaac McFadyen•10/31/24, 9:38 PM

Keep in mind that will ignore all query string not just the incremental cache bust there.

SpunkieOP•10/31/24, 9:39 PM

Ya I thought about that but it kind of defeats why I wanted to use pages. Which is mostly to make it easy to understand and update for non technical users.

S

SpunkieOP•10/31/24, 9:39 PM

But that is prob what I'll do :thisisfine:

I

Isaac McFadyen•10/31/24, 9:39 PM

You could also create a Cache Rule that ignores a specific query string value but I believe it requires a Business plan

M

Mozzy•10/31/24, 9:39 PM

Something I failed to show is that I do need to bust cache if other search params change

I

Isaac McFadyen•10/31/24, 9:39 PM

Yeah one sec then

M

Mozzy•10/31/24, 9:39 PM

ahh

I

Isaac McFadyen•10/31/24, 9:40 PM

Unfortunately it requires Enterprise to exclude specific query params actually.

M

Mozzy•10/31/24, 9:41 PM

would a rewrite middleware that only keeps certain params be enough then?

M

Mozzy•10/31/24, 9:41 PM

Never done rewrites, so not sure it works

I

Isaac McFadyen•10/31/24, 9:42 PM

I believe that would work? Always hard to know because different kinds of Rules run in different orders and there's no real reference that I've seen

actual cache runs at the very end though, if the question is "can I use rules to modify what normal cache uses" pretty sure all of them work, transform headers at least def does

elpupper•10/31/24, 10:24 PM

ok so I'm doing some research and I dont think i get it. is CF for SaaS basically nginx? I cant use workers/worker routes here? Do I have to get my own server that cloudflare can point to?

This seems to do the trick, however cursed it is

export const stripUnusedSearchParams = createMiddleware<{ Bindings: CloudflareBindings }>(async (c, next) => {
  const url = new URL(c.req.url);
  let foundInvalidSearchParams = false;

  for (const key of url.searchParams.keys()) {
    if (!validSearchParams.includes(key)) {
      url.searchParams.delete(key);
      foundInvalidSearchParams = true;
    }
  }

  if (foundInvalidSearchParams) {
    return c.redirect(url.searchParams.size ? `${url.pathname}?${url.searchParams}` : url.pathname, 302);
  }

  await next();
});

Hey, if I have a RPC Target like so

class Foo extends RpcTarget {
  async fetch(request: Request): Promise<Response> {
    return new Response('Hello!');
  }
}

class Foo extends RpcTarget {
  async fetch(request: Request): Promise<Response> {
    return new Response('Hello!');
  }
}

class Foo extends RpcTarget {
  async fetch(request: Request): Promise<Response> {
    return new Response('Hello!');
  }
}

class Foo extends RpcTarget {
  async fetch(request: Request): Promise<Response> {
    return new Response('Hello!');
  }
}

Is there anyway I can just return that response from my worker?

At the moment, I get a type error:

Does the

url

field of the draw object need to be a URL, or can it be an image object/blob? I have a second Worker that generates images, to be used as layers in an overlay, but I need to fetch the images to get dimensions before they're drawn as the overlay

TravisTravis•11/4/24, 6:35 PM

On that same topic, does anyone know how the TCP connection is reused in that example?

They don't seem to be creating a connection explicitly. Is that part handled by hyperdrive?

So routes is not available on pages, only workers? Is that right or am I just blind?
