Stefan Neufeind updated NUTCH-173:
----------------------------------

    Attachment: patch08-new.patch

Here is the 08-patch, corrected to work against nightly from
2006-05-20.
Also fromHost is now only generated if really needed and
nutch-default.xml is patched as well. By the way: Where
should a property for "crawl" be located in the
config-file? In the "fetcher"-section? In that
case please somebody move it up/down or rename the property
before including it in the dev-tree.

But could somebody please review it quickly? I'm not sure
it's 100% correct. Still investigating on my side ...

> There is two major way of crawl in Nutch.
> Intranet Crawl : forbidden all, allow somes few host
> Whole-web crawl : allow all, forbidden few thinks
> I propose a third type of crawl.
> Directory Crawl : The purpose of this crawl is to
manage few thousands of host wihtout managing rules pattern
in UrlFilterRegexp.
> I made two patch for : 0.7, 0.7.1 and 0.8-dev
> I propose a new boolean property in nutch-site.xml :
crawl.ignore.external.links, with false value at default.
> By default this new feature don't modify the behavior
of nutch crawler.
> When you setup this property to true, the crawler
don't fetch external links of the host.
> So the crawl is limited to the host that you inject at
the beginning at the crawl.
> I know there is some proposal of new crawl policy using
the CrawlDatum in 0.8-dev branch. 
> This feature colud be a easiest way to add quickly new
crawl feature to nutch, waiting for a best way to improve
crawl policy.
> I post two patch.
