Hey like i have hosted my vite react app in cloudflare pages and honobackend in the cf workers and there is an issue like when i login the cookie is not present i chrome cookies but in request header it is availabe and also like when i try to logout the cookie is still on the request header and unable to logout on dev no issues. after some reserch i have found like if the front end and backend have different domains like "pages.dev" and "worker.dev" as browser will not save cookie . so is there is a fix for it like without custom domain on dev side the vite proxy works but on production it will not any fix for it

I might be misunderstanding but this seems like a CORS issue?
I have setup a system that used a custom domain on Pages as the origin and had a Worker in front of it, but they had the same top level domain. I don't think it would have mattered, though, since IIRC even subdomains are normally considered separate domains unless you use CORS.

Hello, I’m Allie!OP•3/16/25, 11:54 PM

You write it as a WAF Rule: https://developers.cloudflare.com/waf/custom-rules/

Cloudflare Docs

Custom rules · Cloudflare Web Application Firewall (WAF) docs

Custom rules allow you to control incoming traffic by filtering requests to a zone. You can perform actions like Block or Managed Challenge on incoming requests according to rules you define.

matt•3/17/25, 12:17 AM

is there another option? i shouldn't have to "talk to a (sales) expert" just to write a single, simple firewall rule

matt•3/17/25, 12:20 AM

oh thats just for account-level WAF, not the same as zøne level WAF?

M

matt•3/17/25, 12:30 AM

in the docs, does this rule also allow non-worker requests?

not (cf.worker.upstream_zone in {"" "customer-zone.com"})

not (cf.worker.upstream_zone in {"" "customer-zone.com"})

not (cf.worker.upstream_zone in {"" "customer-zone.com"})

not (cf.worker.upstream_zone in {"" "customer-zone.com"})

if i wanted to allow only requests from workers in my zone, is this one more effective?

not (cf.worker.upstream_zone == "customer-zone.com")

not (cf.worker.upstream_zone == "customer-zone.com")

not (cf.worker.upstream_zone == "customer-zone.com")

I believe you could do something like

cf.worker.upstream_zone != "customer-zone.com"

cf.worker.upstream_zone != "customer-zone.com"

here's an example https://60e6c0e8.docs-bao.pages.dev/ensip/1/

I get a 200 response and a normal preview when pinging the page from a tool like HTTPie, but browsers are redirecting to my project's 404 page. I've tested deploying the same project to other platforms and it works as expected, so I believe its somehow related to Cloudflare
