    "body": "## Symptom\nA download directory served under `/dl/` returned 404 when a user's browser upper-cased the URL (`/DL/FILE.ZIP`). An attempt to cover every casing with one directive:\n\n```\nhandle_path /dl/* /DL/* /Dl/* /dL/* {\n    root * /srv/app/dl\n    file_server browse\n}\n```\nfailed validation:\n\n```\nError: adapting config using caddyfile: parsing caddyfile tokens for 'handle_path': wrong argument count or unexpected line ending after '/DL/*'\n```\n`systemctl reload caddy` failed, and Caddy went on serving the old config. The site stayed up, but the change did nothing.\n\n## Cause\n`handle_path` (like `handle`) accepts **one** inline path matcher, not a list. To match several paths you need a named matcher. Caddy's `path` matcher is case-sensitive, and file names on Linux are too.\n\n## Fix\nUse a named `path_regexp` matcher and strip the prefix yourself with `uri path_regexp`. That replaces what `handle_path` normally does:\n\n```\n@dl path_regexp dl ^/[dD][lL](/.*)?$\nhandle @dl {\n    uri path_regexp ^/[dD][lL]/? /\n    root * /srv/app/dl\n    file_server browse\n}\n```\nThe file name itself is still matched case-sensitively, so add lower/upper-case aliases (symlinks) for the files users will type by hand.\n\n## Verify\n```\ncaddy validate --config /etc/caddy/Caddyfile   # -> Valid configuration\nsystemctl reload caddy\ncurl -sk -o /dev/null -w '%{http_code}\\n' -r 0-99 https://example.com/DL/FILE.ZIP   # 206\ncurl -sk -o /dev/null -w '%{http_code}\\n' -r 0-99 https://example.com/dl/file.zip   # 206\n```\nAfter the change, `/dl/`, `/DL/...` and mixed-case URLs all returned 200/206.\n\n## Notes\nAlways run `caddy validate` before `reload`. A failed reload leaves the old config running, so the edit can look applied when it is not.",
