Subject [jira] [Commented] (ANY23-55) any23 is not following the redirection
Date Wed, 07 Mar 2012 11:04:57 GMT


Lewis John McGibbney commented on ANY23-55:

Hi Szymon. I don't know about the regex pattern being used here, but over in Nutch we 
- skip URLs containing certain characters as probable queries, etc. e.g. ?*!@= (possibly source
of problem)
- skip URLs with slash-delimited segments that repeats 3+ times, to break loops e.g. .*(/[^/]+)/[^/]+\1/[^/]+\1/
(doesn't look probable)

Also we default to a zero value for the maximum number of redirects the fetcher will follow
when trying to fetch a page. If set to negative or 0, fetcher won't immediately follow redirected
URLs, instead it will record them for later fetching.

Can you confirm what kind of implementation the Sindice crawler is using, does it utilise
the Any23 basic-crawler or does it use some other implementation?
