Speed brain shouldn't hit the origin, but it does

So after speed brain was enabled on a free zone we started to see some odd behaviour where som actions are performed multiple times in our application. This is partly our fault for having GET requests "do" stuff but on the other hand we finally tracked it down to Speed Brain causing the links to be prefetched. However reading: https://developers.cloudflare.com/speed/optimization/content/speed-brain/#caveats

Prefetch requests will never reach origin servers.

This seems to be a invalid statement for us. I have logs showing the prefetch header set by Chrome hitting our origins and disabling Speed Brains stops the behaviour immediately. So intentially or not it is causing behaviour it shouldn't....

How do I keep spaces in filenames when using wrangler r2?

My filenames have spaces like "my docs.pdf" and when I run wrangler r2 object put project/my\ docs.pdf --file="/Users/user/Downloads/my docs.pdf" --local but then they show up as my%20docs.pdf and they don't match the file name in the DB. How can I put the actual file name without URL encoding?

Is it possible to connect a private service through cloudflare tunnels?

I understand that Cloudflare Tunnels are typically used to expose services from a private network to the public internet, but what if I want to connect one private network to another? I’ve read the documentation, and I think this is possible in some way, but I'm still pretty confused. I have two instances connected through the same Cloudflare Tunnel. Both instances are running HTTP services, but only instance1 has access to an etcd service that instance2 needs to connect to. I want instance2 to access the etcd service on instance1 using a private hostname, without exposing any IP addresses, and for Cloudflare to handle all the DNS and routing between them privately. Example:...

Zstandard applies to my site somehow

Hi there, I didn't enable compression-rules for my site, https://huntukvisasponsors.com/. However, today I just noticed that my site turns to zstd and caused my website downtime. Right now, I need to manually apply a compression-rules with gzip to prevent this issue. Do you know why?

CF Tunnel works fine when pointing to one domain, but gets http 404 when pointed to another

Hello, so I have been using tunnels for a whileand everything is great. But when I tried to migrate one of my apps from 1 domain (chat.xxx.com) to (chat.yyy.com), despite having a correct CNAME record to point to my tunnel and my sub-domain, I keep getting a http 404 when I got to chat.yyy.com. I have attemped to route another working app to test.yyy.com and its the same result. But once they are back on xxx.com it works, and even on another domain zzz.com. I am quite puzzled and don't really know where to start troubleshooting. ...

Cloudflare connects me so far away

There is a server right near me, I get 1-2ms when pinging 1.1.1.1 but warp and https://speed.cloudflare.com/ connects me so far away. Zero trust is working with this too so it gives so much ping. Since there is no choose server button or anything, how can I fix this?

Protect Redirect Rules with WAF

Hi, I would like to protect a Whataspp Group Join url with a few features, so what I have done is created a hostname and then use Whatsapp redirect feature to redirect the URL to the Whatsapp Group Join URL. This part has worked very well, however the rules that I add to the hostname do not seem to apply (Interactive Challenge, geo restrictions). Is there a better way to do this? Thanks...
