        # about nginx location regex:
        # - https://nginx.org/en/docs/http/ngx_http_core_module.html#location
        # - https://stackoverflow.com/a/59846239
        #   - note in nginx / only means / and no other meaning, so no need \/
        # - ~ means case-sensitive regex
        # about (?:) non-capturing group:
        # - https://manifold.net/doc/radian/why_do_non-capture_groups_exist_.htm
        # - non-capturing group won't capture things inside () which may use later like in sed \1
        #   - note: I don't think sed support ?: , because POSIX ERE and BRE doesn't seem to support ?:
        #   - maybe improve a little bit performance by not storing things (not tested, also I did not read the source code)
