> rules

> Key: NUTCH-2646
> URL: https://issues.apache.org/jira/browse/NUTCH-2646
> Project: Nutch
> Issue Type: Bug
> Components: fetcher, robots
> Affects Versions: 2.3.1, 1.14
> Reporter: Chang Fan
> Assignee: Sebastian Nagel
> Priority: Critical
>
> Redirected robots.txt rules are also cached for the target host. That may
> cause that the correct robots.txt rules are never fetched. E.g.,
> http://wyomingtheband.com/robots.txt redirects to
> https://www.facebook.com/wyomingtheband/robots.txt. Because fetching fails
> with a 404 bots are allowed to crawl wyomingtheband.com. The rules is
> erroneously also cached for the redirect target host www.facebook.com which
> is clear regarding their [robots.txt|https://www.facebook.com/robots.txt]
> rules and does not allow crawling.
> Nutch may cache redirected robots.txt rules only if the path part (in doubt,
> including the query) of the redirect target URL is exactly {{/robots.txt}}.
