- Some casks have URL arguments like "referer" (spelled wrong, that's
intentional in the HTTP spec).
- The audit for one such cask, `iThoughtsX`, was failing because the
"referer" wasn't getting passed through to cURL so the access would
404.

```
❯ brew audit --cask --online --appcast --signing 'ithoughtsx'
