A sample code to run a couple of crawler algorithms is available as
spider.crawl.Tester (see in appropriate folder under
sources). Make sure that you edit the code to put your e-mail
address within this class. The e-mail address will be used with each
outgoing HTTP request.
There are parts of the code that intentionally slow down the crawlers. They are not without a purpose. The code respects the Robot Exclusion Protocol and spreads the crawling load over many remote Web servers. The code is under development.
To learn more about the design and details of the code you may read:
