This is just in case a page forward the parser to a new url.
Real url filtering is done in (nutch .8):
ParseOutputFormat line:100.

I am checking also Fetcher, it seems strange for me:
Case ProtocolStatus.MOVED:
Case ProtocolStatus.TEMP_MOVED:
handleFetch(fle, output);
String newurl = pstat.getMessage();
newurl = URLFilters.filter(newurl);
So, we are calling "handleFetch" before "filter"... Error?
EnabledHost - sends redirect to DisabledHost
DisabledHost - parsed(!), links to unknown-hosts are probably
stored (in not
disabled explicitly)

We have following code:
org.apache.nutch.parse.ParseOutputFormat.java
...
[94] toUrl = urlNormalizer.normalize(toUrl);
[95] toUrl = URLFilters.filter(toUrl);
...
It normalizes, then filters normalized URL, than writes it to /
crawl_parse
In some cases normalized URL is not same as raw URL, and it is not
filtered.

It will also be generated in case if non-filtered page have "Send
Redirect"
to another page (which should be filtered)...
I have same problem in my modified DOMContentUtils.java,
...
if (url.getHost().equals(base.getHost())) { outlinks.add
(..........); }
...
- it doesn't help, I see some URLs from "filtered" hosts again...

Hi Stefan,
As I understand, when you use 'nutch generate' to
generate fetch list, it doesn't call urlfilter. Only
in 'nutch updatedb' and 'nutch fetch' it does call
urlfilter. So the page after 30 days will be generated
even if you use url filter to filter it.
Best regards,
Keren

not if you filter it in the url filter.
There is a database based url filter I think in the
jira somewhere
somehow, this can help to filter larger lists of
urls.

Hi Stefan,
Thank you. You are right. I have to use a url
filter
and remove it from the index. But after 30 days
later,
the page will be generated again in generating
fetch
list.
Thanks,
Keren

Use a url filter instead and remove it from the
index.
Removing from webdb makes no sense.

Hi everyone,
It took about 10 minutes to remove a page from
WEBDB
using WebDBWriter. Does anyone know other method
to
remove a page, which is faster.
Thanks,
Keren
