Logfile - Time of DNS Validity

Time of DNS ValidityEach entry in the DNS cachefile is time-stamped and will be discarded after some time. The value of this parameter is the number of days after which a resolved domain name is considered invalid and the DNS-lookup is performed again. In most cases it is reasonable to set this value to 30 days, as most ISP's do not change their domain names very often.

Please note: Only the Stone Steps version of the Webalizer is able to interpret this parameter.
