   * ``temporaryFailureTTL=60``: int - On a SERVFAIL or REFUSED from the backend, cache for this amount of seconds.
   * ``truncatedTTL=0``: int - On a truncated (TC=1, no records) response from the backend, cache for this amount of seconds. 0, the default, means that truncated answers are not cached.
   * ``cookieHashing=false``: bool - If true, EDNS Cookie values will be hashed, resulting in separate entries for different cookies in the packet cache. This is required if the backend is sending answers with EDNS Cookies; otherwise, a client might receive an answer with the wrong cookie.
-  * ``skipOptions={12}``: Extra list of EDNS option codes to skip when hashing the packet (if ``cookieHashing`` above is false, EDNS cookie option number will be added to this list internally).
+  * ``skipOptions={10, 12}``: Extra list of EDNS option codes to skip when hashing the packet (if ``cookieHashing`` above is true, EDNS cookie option number will be removed from this list internally).
   * ``maximumEntrySize=4096``: int - The maximum size, in bytes, of a DNS packet that can be inserted into the packet cache. Default is 4096 bytes, which was the fixed size before 1.9.0, and is also a hard limit for UDP responses.
   * ``payloadRanks={}``: List of payload size used when hashing the packet. The list will be sorted in ascending order and searched to find a lower bound value for the payload size in the packet. If found then it will be used for packet hashing. Values less than 512 or greater than ``maximumEntrySize`` above will be discarded. This option is to enable cache entry sharing between clients using different payload sizes when needed.
