Sebastian Nagel commented on NUTCH-1927: ---------------------------------------- Hi Chris, the class WhiteListRobotRules seems to me still overly complex. It should be possible to keep the cache as is and only put a reference to light-weight singleton RobotRules object (such as created by the default constructor of the WhiteListRobotRules) in case a host is whitelisted. Also I do not understand why getCrawlDelay() needs to store the last URL: the Crawl-Delay specified in the robots.txt can be used to override the default delay/interval when a robot/crawler accesses the same host successively: it's a fixed value and does not depend on any previous fetches. Don't know whether this is a problem: we (almost) everywhere use org.slf4j.Logger and not java.util.logging.Logger. > Create a whitelist of IPs/hostnames to allow skipping of RobotRules parsing > --------------------------------------------------------------------------- > > Key: NUTCH-1927 > URL: https://issues.apache.org/jira/browse/NUTCH-1927 > Project: Nutch > Issue Type: New Feature > Components: fetcher > Reporter: Chris A.
