🌐 Web query:
official ASGI HTTP specification header names lowercased must not mandated mixed-case headers
💡 Result:
The official ASGI HTTP spec **does not require incoming request header names to be lowercase**: it says they “should be lowercased, but it is not required,” and servers should preserve their case where possible. ([asgi.readthedocs.io](https://asgi.readthedocs.io/en/latest/specs/www.html))
But for **outgoing HTTP responses**, the spec says header names **must be lowercase**. So mixed-case response header names are not compliant with the current spec. ([asgi.readthedocs.io](https://asgi.readthedocs.io/en/latest/specs/www.html))

🌐 Web query:
official Uvicorn source h11_impl h2_impl incoming request headers lower() ASGI scope
💡 Result:
In Uvicorn’s current `main` source:
- **HTTP/1.1 (`h11_impl.py`):** Incoming header names are lowercased with `key.lower()` and stored as `(bytes, bytes)` pairs. Those pairs are assigned to `scope["headers"]` before the scope is passed to the ASGI app. ([github.com](https://github.com/Kludex/uvicorn/blob/main/uvicorn/protocols/http/h11_impl.py))
- **HTTP/2:** I couldn’t find a file named `h2_impl.py` in the current source. The current HTTP/2 implementation appears to be `zttp_h2_impl.py`; the server’s protocol references identify that file as `ZttpH2Protocol`. ([github.com](https://github.com/Kludex/uvicorn/blob/main/uvicorn/server.py?utm_source=openai))
So the `h11` source directly confirms lowercasing; the corresponding HTTP/2 header handling would need to be checked in `zttp_h2_impl.py` (the current filename, not `h2_impl.py`). The source links are for `main`, not a specified release or commit.

ASGI 명세와 Uvicorn 동작 범위를 구분해 문서를 수정하세요.
이 저장소는 Uvicorn을 사용하며, 현재 HTTP/1.1 경로는 ASGI scope에 넣기 전에 헤더 이름을 소문자로 변환합니다. 따라서 main.py의 정확한 비교가 지원되는 실행 경로에서 유효한 인증 요청을 거부한다는 주장은 성립하지 않습니다.
반면 ASGI 명세 전체가 헤더 이름의 소문자화를 보장한다는 .jules/bolt.md의 표현은 부정확합니다. 최적화 근거를 Uvicorn의 동작으로 한정하세요.
문서 수정 예시
-**Learning:** Accessing `request.url.scheme` triggers expensive URL parsing. Also ASGI servers guarantee that header names in the ASGI scope are already lowercased byte strings, so redundant `.lower()` calls on header names add measurable overhead.
-**Action:** Use `request.scope.get('scheme', 'http')` to access the scheme directly and avoid redundant `.lower()` calls on header names when iterating through them.
+**Learning:** Accessing `request.url.scheme` triggers expensive URL parsing. In this project, Uvicorn lowercases incoming header names before placing them in the ASGI scope, so redundant `.lower()` calls add measurable overhead.
+**Action:** Use `request.scope.get('scheme', 'http')` to access the scheme directly. Avoid redundant `.lower()` calls on header names only when the configured server provides this normalization.📍 Affects 2 files

💡 What:
request.url.scheme대신request.scope.get("scheme", "http")를 사용하여 불필요한 URL 파싱을 방지하고, ASGI 명세에 따라 헤더 이름이 소문자임을 활용하여name.lower()호출을 제거했습니다.🎯 Why: 매 요청마다 URL 객체를 파싱하고 헤더 이름을 소문자로 변환하는 불필요한 비용을 절감하기 위함입니다.
📊 Impact: 헤더 반복문에서 문자열 변환 할당이 줄어들고 URL 파싱을 우회하여 응답 처리 속도가 개선됩니다.
