The non-JS challenge[0] mentioned in the blog post is one based on HTTP meta refresh. The (hypothetical) WebAssembly challenge is proposed as an improvement on the existing JS proof-of-work challenge[1].
Yes but without JS (or wasm), the meta refresh option can't actually do any work, right?
I mean, parsing a meta refresh tag is not exactly rocket science... aren't most scrapers already headless browsers anyway? I know I have seen several big proxy providers offering that as a service to defeat cloudflare.
