Parsechecker and indexchecker should report the protocol status when the fetch was not successful (status other than 200/ok).
In case of a redirect, the protocol status contains the URL a redirect points to. Usually, this URL should be checked instead of the original one which is not indexed. The content of a redirect response is less useful (and often empty):
% nutch indexchecker http:fetching: http:parsing: http:contentType: text/html
