org.archive.modules.canonicalize.StripWWWNRule

All Implemented Interfaces:

Serializable, CanonicalizationRule, HasKeyedProperties

public class StripWWWNRule
extends BaseRule

Strip any 'www[0-9]*' found on http/https URLs IF they have some path/query component (content after third slash). Top 'slash page' URIs are left unstripped: we prefer crawling redundant top pages to missing an entire site only available from either the www-full or www-less hostname, but not both.
