    <!-- keyed – The quota_key "key" is passed in the query parameter,
            and the quota is tracked separately for each key value.
        For example, you can pass a username as the key,
            so the quota will be counted separately for each username.
        Using keys makes sense only if quota_key is transmitted by the program, not by a user.

        You can also write <keyed_by_ip />, so the IP address is used as the quota key.
        (But keep in mind that users can change the IPv6 address fairly easily.)

        Instead of <keyed_by_ip /> you can use <keyed_by_forwarded_ip />, so the address
        from the X-Forwarded-For header is used as the quota key.

        For both <keyed_by_ip /> and <keyed_by_forwarded_ip /> you can additionally specify
        <ipv4_prefix_bits> and <ipv6_prefix_bits> to group clients by subnet instead of by a
        single address: the IP address is masked to the given prefix length before being used
        as the quota key. For example, <ipv4_prefix_bits>24</ipv4_prefix_bits> shares one bucket
        across a /24 IPv4 subnet, and <ipv6_prefix_bits>64</ipv6_prefix_bits> across a /64 IPv6
        subnet. These elements can only be used together with <keyed_by_ip /> or
        <keyed_by_forwarded_ip />.
