If the client tries to go to `/items`, by default, it would be redirected to `/items/`.

But before setting the *CLI Option* `--forwarded-allow-ips` it could redirect to `http://localhost:8000/items/`.

But maybe your application is hosted at `https://mysuperapp.com`, and the redirection should be to `https://mysuperapp.com/items/`.

By setting `--proxy-headers` now FastAPI would be able to redirect to the right location. 😎

```
https://mysuperapp.com/items/

  She stretched herself up on tiptoe, and peeped over the edge of
the mushroom, and her eyes immediately met those of a large
caterpillar, that was sitting on the top with its arms folded,
quietly smoking a long hookah, and taking not the smallest notice
of her or of anything else.
