Nesta seção, veremos como usar outros middlewares.

## Adicionando middlewares ASGI

Como o **FastAPI** é baseado no Starlette e implementa a especificação <abbr title="Asynchronous Server Gateway Interface">ASGI</abbr>, você pode usar qualquer middleware ASGI.

O middleware não precisa ser feito para o FastAPI ou Starlette para funcionar, desde que siga a especificação ASGI.

		} else { // In a hole fragment
			nf = holeEnd - sr.pos
			if sr.physicalRemaining() == 0 {
				writeLastByte = true
				nf--
			}
			_, err = ws.Seek(nf, io.SeekCurrent)
		}
		sr.pos += nf
		if sr.pos >= holeEnd && len(sr.sp) > 1 {
			sr.sp = sr.sp[1:] // Ensure last fragment always remains
		}
	}

	// If the last fragment is a hole, then seek to 1-byte before EOF, and

## Submitting PRs

1. **Title and Summary**:
   - Use a scannable title: `[Subsystem] Action Description #Issue` (e.g., `[IAM] Add role-based access control #567`).
   - Include context in the summary: what changed, why, and any issue references.
   - Use `[WIP]` for in-progress PRs to avoid premature merging or choose GitHub draft PRs.

2. **Commits**:
