Cloudflare + WebFlow + AWS

Hello,

I'm trying to solve following routing design and need help from the community:

Domain: https://staging.example.com
Request coming to https://staging.example.com/app/* must be routed AWS IP or DNS
All other requests coming to https://staging.example.com/ must be routed to WebFlow which is where primary marketing website runs.

Please suggest how this could be achieved?

I've tried following approaches and faced different issues:
Approach #1 :

Created CNAME for staging.example.com and pointed to WebFlow's URL, but Cloudflare is throwing Error 1014 CNAME Cross-User Banned.

Approach #2:

Added subdomain inside the Webflow which further created CNAME in Cloudflare.
It got the website working, but then Proxy was disabled which restrict cloudflare to do further rule based routing.

Assuming the domain is onboarded and active in your own Cloudflare account, first set the DNS record for stagingstaging to a CNAME pointing to cdn.webflow.comcdn.webflow.com as "DNS only". Check this works first. A 1014 error here means your staging.example.comstaging.example.com is not set up as a custom domain on Webflow. Get that working first.

Then proxy that record, ensure it continues to work (there shouldn't be any issue there). By default all requests go to Webflow.

On AWS you will need to serve the content through another subdomain, say staging-awsstaging-aws, proxied or not is up to you. Start "DNS only" if unsure.

Create a Cloudflare Worker with a route https://staging.example.com/app/*https://staging.example.com/app/* (or better if on a paid plan, a Snippet to act on the same URL). That Worker/Snippet then makes the request to AWS and returns the response. See here for an example... https://developers.cloudflare.com/rules/snippets/examples/route-and-rewrite/
