Jeff Bowden updated NUTCH-98:
-----------------------------
Attachment: RobotRulesParser.java.diff
Patch to fix interpretation of robots.txt
> RobotRulesParser interprets robots.txt incorrectly
> --------------------------------------------------
>
> Key: NUTCH-98
> URL: http://issues.apache.org/jira/browse/NUTCH-98
> Project: Nutch
> Type: Bug
> Components: fetcher
> Versions: 0.7
> Reporter: Jeff Bowden
> Priority: Minor
> Attachments: RobotRulesParser.java.diff
>
> Here's a simple example that the current RobotRulesParser gets wrong:
> User-agent: *
> Disallow: /
> Allow: /rss
> The problem is that the isAllowed function takes the first rule that matches
> and incorrectly decides that URLs starting with "/rss" are Disallowed. The
> correct algorithm is to take the *longest* rule that matches. I will attach
> a patch that fixes this.
