But web browsers don't crawl a single site exhaustively and quickly, rather they make a bunch of requests for resources tied to a single page, then wait relatively long time, and then make another bunch of requests ... So, the request pattern is still more "fair" than in the case of a mad crawler. -- Best regards, Andrzej Bialecki <>< ___. ___ ___ ___ _ _ __________________________________ [__ || __|__/|__||\/| Information Retrieval, Semantic Web ___|||__|| \| || | Embedded Unix, System Integration http://www.sigram.com Contact: info at sigram dot com ------------------------------------------------------------------------- Using Tomcat but need to do more?
