One of the rules to ensure it works: > The page requested by the prefetch does not invoke a Worker. I guess this restriction kind of makes sense for this? Funny enough though, some of the best speed optimization Cloudflare stuff only works with Workers if you use a Fetch (aka, you must have an origin!). The Worker Cache API for example doesn't support Polish/Mirage or many other Cloudflare features.
