Otis Gospodnetic commented on NUTCH-731:
----------------------------------------

People have redirects on their robots.txt?  Wow.  Do you have an example of that handy, by
any chance?

> 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)
