Is it true that the cache api may not store the content-length header if I'm caching a stream?

Hello everyone, I have what I think is a pretty basic question about workers and environment variables / secrets. I've had a couple instances where my runtime environment variables and secrets disappear in the dashboard and I have to re-add them. I'm adding my runtime environment variables (not secrets) to my wrangler.jsonc as vars and my assumption was that once I add my secrets in the dashboard they just stay there until I delete or rotate them. Is my understanding correct? Are there any configuration things that could be causing this behavior? I currently have my workers set to auto-build after a merge in my git branch (not deploying from IDE). Any info helps, thanks!

Actually, I'm sorry, one follow up to cement my understanding, does this mean that framework-based static assets workers are also boiled down to one worker that is composed of all the static assets, the SSR calls, AND one conventional worker definition deployed as one bundle? I guess this is a roundabout way of asking how static asset routing works in that case since my vague mental model is that SSR elements in a framework are neither asset routes nor calls to the main worker definition. Like are those routes treated as, to coin a terrible confusing phrase, static dynamic assets?

Static assets aren't included in the bundle. Basically:

Bundle: Functions (for Pages), or your Worker + any deps in the Worker + anything the Worker directly imports
Deploy alongside: everything else (images, audio, html, whatever that is not imported into your Worker)

I

Isaac McFadyen•3/28/25, 7:39 PM

The "deploy alongside" actually uses KV but it's all handled for your by the platform (either Pages or Workers Assets)

I think I get it, and I apologize if this is annoyingly repatative, into which of those two buckets does an SSR endpoint fall? Or more practically: Is anything that's not a freely served asset counted/billed as a worker invocation?

Isaac McFadyen•3/28/25, 7:45 PM

SSR would be part of the bundle and which is billed as a Worker request because the Worker is doing some work (to SSR) the files.

I

Isaac McFadyen•3/28/25, 7:45 PM

For example, if you rendered a page and served it with SSR, the request for that page would be billed, and then if the page was then sent to the browser and then an image on that page was loaded, that would be an asset request not a Worker request.

The Cache API should be able to store streaming objects but there's a limit of 512MB for the Cache API which you may be running into?

I am able to store the object (they are under 512mb, though I wasn't aware of that limit). The issue I'm referring to is when i send a response object, and set the content-length if it's a streaming response, the content-length is ignored and it winds up blank at the client.

I

Isaac McFadyen•3/30/25, 12:14 AM

Per the official spec, if the response is streamed it's not allowed to have a Content-Length (https://datatracker.ietf.org/doc/html/rfc9112#section-6.2) so I expect that's why Cloudflare's stripping it before sending it to the client.

I

Isaac McFadyen•3/30/25, 12:14 AM

Most clients should handle streaming responses properly though, what client is this?

first thing came to my mind is Next.js support, I know you could deploy open next js; and there is indeed guides to use opennextjs on to existing nextjs apps, but it isn't clear if it's fully compatible with current nextjs version (that is deployed to cloudflare pages) or not.
