404 on importing type declarations files from pika.dev using Deno 1.0.1

[mdubourg001]

Hi there,

I've been working on some tooling that requires the use of a module I import from cdn.pika.dev. as follows:

import { parse } from "https://cdn.pika.dev/html5parser@^1.1.0";

These imports used to work when I was using Deno 1.0.0-rc3, but ever since I upgraded to the last Deno release (1.0.1), these imports break to a 404 error:

error: Import 'https://cdn.pika.dev/-/html5parser@v1.1.2-0fAkC9viFOtRB3VnrC0m/dist=es2019,mode=types/types.d.ts' failed: 404 Not Found

As mentioned in this issue I commented on on the pika/cdn repo, I first thought the issues came from Pika, but I just tried to downgrade to Deno 1.0.0-rc3, and the imports work great again.

Must be related to #5029; needs more investigation

@mdubourg001 I'm not sure if that's a Deno bug, I've written down my findings: skypackjs/skypack-cdn#8 (comment)

Okay I found the issue after all; #5029 introduced bad redirection handling which causes this problem. I'll fix it.
