Chris A. Mattmann commented on NUTCH-2144:
------------------------------------------

I am +1 for this patch, and enabled only by the user (and not by default). This 
is a critical patch for us in MEMEX and I think it adds a lot of value here to 
the community.

[~lewismc] and I will work to get this committed in the next 48 hours. Thank 
you [~thammegowda]!

> Create a rule based urlfilter plugin that allows focused crawler 
> (db.ignore.external.links=true) to fetch static resources from external 
> domains.
> The generalized version of this: This plugin should permit interesting URLs 
> from external domains (by overriding db.ignore.external). The interesting 
> urls are decided from a combination of regex and mime-type rules.
> Concrete use case:
>   When using Nutch to crawl images from a set of domains, the crawler needs 
> to fetch all images which may be linked from CDNs and other domains. In this 
> scenario, allowing all external links and then writing hundreds of regular 
> expressions is not feasible for large number of domains.
