```

But FastAPI (actually Starlette) provides a simpler way to do it that makes sure that the internal middlewares handle server errors and custom exception handlers work properly.

For that, you use `app.add_middleware()` (as in the example for CORS).

```Python
from fastapi import FastAPI
from unicorn import UnicornMiddleware

app = FastAPI()

    }

        // The normalization removes all duplicate backslashes, so \\\\server becomes \server
        // This test validates that paths which should be UNC but aren't detected due to normalization

        }
