Andrzej Bialecki commented on NUTCH-353:
-----------------------------------------
I believe the patch in NUTCH-273 fixes a large part of the problem, that you
describe - we record the fact that there was a redirect, and Indexer indexes
only the final page.
The other parts though (correct treatment of inlink information, and selection
of representative pages for chains of redirects) is not addressed yet.
> pages that serverside forwards will be refetched every time

> Pages that do a serverside forward are not written with a status change back
> into the crawlDb. Also the nextFetchTime is not changed.
> This causes a refetch of the same page again and again. The result is nutch
> is not polite and refetching the forwarding and target page in each segment
> iteration. Also it effects the scoring since the forward page contribute it's
> score to all outlinks.
