[jira] Updated: (NUTCH-926) Nutch follows wrong url in
[ https://issues.apache.org/jira/browse/NUTCH-926?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Marco Novo updated NUTCH-926:
-----------------------------
Description:
We have nutch set to crawl a domain urllist and we want to fetch only passed domains (hosts) not subdomains.
So
WWW.DOMAIN1.COM
..
..
..
WWW.RIGHTDOMAIN.COM
..
..
..
..
WWW.DOMAIN.COM
We sets nutch to:
NOT FOLLOW EXERNAL LINKS
During crawling of WWW.RIGHTDOMAIN.COM
if a page contains
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title></title>
<META http-equiv="refresh" content="0;
url=http://WRONG.RIGHTDOMAIN.COM">
</head>
<body>
</body>
</html>
Nutch continues to crawl the WRONG subdomains! But it should not do this!!
During crawling of WWW.RIGHTDOMAIN.COM
if a page contains
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title></title>
<META http-equiv="refresh" content="0;
url=http://WWW.WRONGDOMAIN.COM">
</head>
<body>

</html>
Nutch continues to crawl the WRONG domain! But it should not do this! If that we will spider all the web....
We think the problem is in org.apache.nutch.parse ParseOutputFormat. We have done a patch so we will attach it

We think the problem is in Fetcher class in method handleRedirect but we are not able to fix that
