<b>Description:</b>
<p>

  
The following list explains the supported follow-modes:<br><br><b>0 - The crawler will follow EVERY link, even if the link leads to a different host or domain.</b><br>If you choose this mode, you really should set a limit to the crawling-process (see limit-options),<br>otherwise the crawler maybe will crawl the whole WWW!<br><br><b>1 - The crawler only follow links that lead to the same domain like the one in the root-url.</b><br>E.g. if the root-url (setURL()) is "http://www.foo.com", the crawler will follow links to "http://www.foo.com/..."<br>and "http://bar.foo.com/...", but not to "http://www.another-domain.com/...".<br><br><b>2 - The crawler will only follow links that lead to the same host like the one in the root-url.</b><br>E.g. if the root-url (setURL()) is "http://www.foo.com", the crawler will ONLY follow links to "http://www.foo.com/...", but not<br>to "http://bar.foo.com/..." and "http://www.another-domain.com/...". <b>This is the default mode.</b><br><br><b>3 - The crawler only follows links to pages or files located in or under the same path like the one of the root-url.</b><br>E.g. if the root-url is "http://www.foo.com/bar/index.html", the crawler will follow links to "http://www.foo.com/bar/page.html" and<br>"http://www.foo.com/bar/path/index.html", but not links to "http://www.foo.com/page.html".
