------------------------------------
A simple and wise solution. Thanks.
> protocol-http fails to follow redirections when an HTTP response body is
> invalid
> --------------------------------------------------------------------------------

> Key: NUTCH-2557
> URL: https://issues.apache.org/jira/browse/NUTCH-2557
> Project: Nutch
> Issue Type: Sub-task
> Affects Versions: 1.14
> Reporter: Gerard Bouchar
> Priority: Major
> Fix For: 1.15
>
>
> If a server sends a redirection (3XX status code, with a Location header),
> protocol-http tries to parse the HTTP response body anyway. Thus, if an error
> occurs while decoding the body, the redirection is not followed and the
> information is lost. Browsers follow the redirection and close the socket
> soon as they can.
> * Example: this page is a redirection to its https version, with an HTTP
> body containing invalidly gzip encoded contents. Browsers follow the
> redirection, but nutch throws an error:
> ** [http://www.webarcelona.net/es/blog?page=2]
>
> The HttpResponse::getContent class can already return null. I think it should
> at least return null when parsing the HTTP response body fails.
> Ideally, we would adopt the same behavior as browsers, and not even try
> parsing the body when the headers indicate a redirection.
