* feat(lib/challenge): expose ResponseWriter to challenge issuers Signed-off-by: Xe Iaso <me@xeiaso.net> * feat(metarefresh): randomly use the Refresh header There are several ways to trigger an automatic refresh without JavaScript. One of them is the "meta refresh" method[1], but the other is with the Refresh header[2]. Both are semantically identical and supported with browsers as old as Chrome version 1. Given that they are basically the same thing, this patch makes Anubis randomly select between them by using the challenge random data's first character. This will fire about 50% of the time. I expect this to have no impact. If this works out fine, then I will implement some kind of fallback logic for the fast challenge such that admins can opt into allowing clients with a no-js configuration to pass the fast challenge. This needs to bake in the oven though.

Overview
Anubis is a Web AI Firewall Utility that weighs the soul of your connection using one or more challenges in order to protect upstream resources from scraper bots.
This program is designed to help protect the small internet from the endless storm of requests that flood in from AI companies. Anubis is as lightweight as possible to ensure that everyone can afford to protect the communities closest to them.
Anubis is a bit of a nuclear response. This will result in your website being blocked from smaller scrapers and may inhibit "good bots" like the Internet Archive. You can configure bot policy definitions to explicitly allowlist them and we are working on a curated set of "known good" bots to allow for a compromise between discoverability and uptime.
In most cases, you should not need this and can probably get by using Cloudflare to protect a given origin. However, for circumstances where you can't or won't use Cloudflare, Anubis is there for you.
