> Please note that also URLs redirected by meta refresh redirection do have invalid scores. For such URLs a CrawlDatum is created on the lines 157-177 of ParseOutputFormat.java (http://svn.apache.org/viewvc/nutch/branches/branch-1.3/src/java/org/apache/nutch/parse/ParseOutputFormat.java?view=markup). The new CrawlDatum's score isn't set anywhere after the creation so it's 1.0f as can be seen on the line 122 of CrawlDatum.java (http://svn.apache.org/viewvc/nutch/branches/branch-1.3/src/java/org/apache/nutch/crawl/CrawlDatum.java?view=markup).
> It's another question whether the redirected URL's score should be just passed to the new URL or should the redirection be considered as a link in which case the new URL's score would be 'originalScore' / ('numberOfOutlinks' + 1).
