CORS + caching proxy for *.wikidot.com and *.wdfiles.com

Fetch Wikidot pages and files from browser JavaScript (normally blocked by
CORS), with caching to ease the load on Wikidot.

Supports read-only operations (GET) on public resources only.

You do not need to use a CORS proxy when accessing Wikidot resources by any
means other than browser Javascript.

Usage: in browser-side fetches, pass the encoded target URL as ?url=:

  https://wikidot.croquembouche.net/?url=THE_ENCODED_ADDRESS

E.g. to fetch the text of a CSS code block:

  const target = "https://scp-wiki.wikidot.com/component:croqstyle/code/1";
  const proxied = "https://wikidot.croquembouche.net/?url=" + encodeURIComponent(target);
  const response = await fetch(proxied);
  const text = await response.text();  // or .blob() for images

Caching: responses are reused for up to an hour by default. Override per
request with the X-Proxy-Cache header:

  await fetch(proxied, { headers: { "X-Proxy-Cache": "max-age=3600" } });

  max-age=3600    accept a cached copy up to 1h old (very efficient)
  max-age=30      accept a cached copy up to 30s old (kinda efficient)
  no-cache        always fetch a fresh copy (inefficient, very impolite)

X-Cache response header tells you if it was cached or not (HIT / MISS).

Rate limit: 60 requests per 10 seconds per IP, then HTTP 429.
