> Key: NUTCH-2776
> URL: https://issues.apache.org/jira/browse/NUTCH-2776
> Project: Nutch
> Issue Type: Improvement
> Components: fetcher
> Affects Versions: 1.16
> Reporter: Sebastian Nagel
> Assignee: Sebastian Nagel
> Priority: Major
> Fix For: 1.17
>
>
> If fetcher follows redirect (http.redirect.max > 0), it may happen that many
> redirects of a site point to the same URL. In this situation, it might be
> good if fetcher could temporarily (for a configurable time period)
> deduplicate the redirect targets and skip all redirects except the first one.
> Typical examples of duplicated redirect targets are:
> - instead of responding with HTTP status 404:
> {noformat}
> /
> /resource-not-found
> /search/
> /404
> /error/not-found
> /err/notfound.html{noformat}
> - a page to accept/decline cookies
> {noformat}
> /cookie_usage.php
> {noformat}
