>                 URL: https://issues.apache.org/jira/browse/NUTCH-2554
>             Project: Nutch
>          Issue Type: Bug
>            Reporter: Gerard Bouchar
>            Priority: Major
>
> The parserchecker (org.apache.nutch.parse.ParserChecker) calls _URLUtil.toASCII_ on the url it is given, reencoding already percent-encoded URLs.
> For instance, let's say we want to query _http://example.com_, passing a GET parameter with name 'q' and value '/'. '/' is a special character, and thus has to be encoded before being sent.
> If we pass '[_http://example.com/?q=/_'|http://example.com/?q=/%27] to the parserchecker, then it doesn't encode the '/', and tries to fetch the URL as is, which is invalid.
> If we try to encode the parameter beforehand, and call the parsechecker with 'http://example.com/?q=%2F', then it encodes the '%' sign to '%25', and thus fetches '[http://example.com/?q=%252F'.|http://example.com/?q=%252F%27.]
> This actually makes it impossible to fetch the correct URL (http://example.com/?q=%2F) from the parsechecker.
