Hi everyone,

Has anyone run across a captcha vmod, or possible implementation methods?
I'm trying to implement a function similar to how Cloudflare has to
challenge certain requests with a captcha before allowing the request to go
to the backend, but I'm not having much luck. Any thoughts or suggestions
are greatly appreciated!
