#Takes a boolean or "no-negative" as argument. If "yes" (the default), resolving a domain name which already got queried earlier will return the previous result as long as it is still valid, and thus does not result in a new network
#request. Be aware that turning off caching comes at a performance penalty, which is particularly high when DNSSEC is used. If "no-negative", only positive answers are cached.

#Default: yes
