In this snippet ```python if header.startswith("X-Forwarded-"): section = header.removeprefix("X-Forwarded-") ``` the `startswith()` check is unnecessary. If `header` doesn't start with "X-Forwarded-" then `header.removeprefix("X-Forwarded-")` just returns `header`. Nice summary doc, with good examples.
