__cf_bm)www.xxx.com and proxy.xxx.com (same domain, just different subdomains)www.xxx.com is where all requests enter from normal users, and where we have our worker runningproxy.xxx.com is where the above worker calls to fetch pages, resources, etc. (Just a reverse proxy essentially) This is not another worker, it is essentially the origin server.proxy.xxx.com. Everything works as expected. Our cache is hit, we get Age headers as we expect, etc. No issues.proxy.xxx.com to include the __cf_bm cookie, and seems to instruct Cloudflare not to cache the response, because it has a Set-Cookie header, completely defeating the purpose of us enabling tiered cache.
