Subject [jira] [Commented] (NUTCH-1098) better url-normalizer basic
Date Tue, 01 Nov 2011 15:23:32 GMT

    [ https://issues.apache.org/jira/browse/NUTCH-1098?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13141233#comment-13141233

Radim Kolar commented on NUTCH-1098:
------------------------------------

1. patch --ignore-whitespace

2. only small portion of existing crawled segments will become invalid and data in crawled
segments has short lifetime anyway - They are indexed and deleted

3. decoding %2f into / is good idea because ASP.NET generated redirects comes with / encoded
as %2f. (this was initially included but removed due to Markus complain)

4. No, i am not going to split such trivial patch like this
