Worker is lowercasing URL using Response.redirect

Using this code:

async function redirect(request) {
    const uri = request.url.replace(/^https:\/\/.*?\//gi, "/");
    console.log(uri);
    let url = "https://mirrors.lifehacker101.net/flashcard-archive/" + uri;
    console.log(url);

    return Response.redirect(url);
}

async function redirect(request) {
    const uri = request.url.replace(/^https:\/\/.*?\//gi, "/");
    console.log(uri);
    let url = "https://mirrors.lifehacker101.net/flashcard-archive/" + uri;
    console.log(url);

    return Response.redirect(url);
}

it correctly logs:

/TEST.zip
https://mirrors.lifehacker101.net/flashcard-archive//TEST.zip

/TEST.zip
https://mirrors.lifehacker101.net/flashcard-archive//TEST.zip

However it is doing this instead:

alt-svc: h3=":443"; ma=86400

This causes 404 on the target location's web server. Is there something going on that I don't know about causing this?

How to have exact opposite behaviour of CF Pages pretty URL??

https://wiki-8j2.pages.dev https://github.com/flashcarts/wiki I've found that Cloudflare Pages' built in pretty URL system will rewrite links to .html to remove this suffix. I want to have the exact opposite: if a user accesses the URL via pretty URL format, I want it to automatically append .html. I would rather user have the full path; the only reason the pretty URL is relevant for me is to make internal linking in markdown not a huge PITA to do. While I haven't tried it, I am naively thinking that if I make use of a _redirects file for this, it would cause an infinite loop of _redirects redirecting to .html and CF Pages 308-ing to non-.html. Is there a way to get around this?

WAF on non-known bots trigger on a web browser GET request

While playing around with Cloudflare security rules for R2, I came across the Known Bots flag. I've tested this in a few angles, and it appears that doing any action against (not cf.client.bot) seems to also trigger on Firefox and Microsoft Edge. Some questions for that: - Are plain ol' browsers also considered bots? - If I am using a public bucket, do I have no choice but to let bots fly so that a standard web browser can do its job? (and sacrifice free R2 ops count for this?)
