Subject [jira] Created: (NUTCH-731) Redirection of robots.txt in RobotRulesParser
Date Fri, 03 Apr 2009 17:54:13 GMT
Redirection of robots.txt in RobotRulesParser
---------------------------------------------

                 Key: NUTCH-731
                 URL: https://issues.apache.org/jira/browse/NUTCH-731
             Project: Nutch
          Issue Type: Improvement
          Components: fetcher
    Affects Versions: 1.0.0
            Reporter: Julien Nioche


The patch attached allows to follow one level of redirection for robots.txt files. A similar
issue was mentioned in NUTCH-124 and has been marked as fixed a long time ago but the problem
remained, at least when using Fetcher2 . Mathijs Homminga pointed to the problem in a mail
to the nutch-dev list in March.

I have been using this patch for a while now on a large cluster and noticed that the ratio
of robots_denied per fetchlist went up, meaning that at least we are now getting restrictions
we would not have had before (and getting less complaints from webmasters at the same time)
