> Hi,
> I have written (not much) a new plugin, based on the URLFilter interface: urlfilter-db .
> The purpose of this plugin is to filter domains, i.e. I would like to crawl the world but to fetch only certain domains.
> The plugin uses a caching system (SwarmCache, easier to deploy than JCS) and on the back-end a database.
> For each url
> filter is called
> end for
> filter
> get the domain name from url
> call cache.get domain
> if not in cache try the database
> if in database cache it and return it
> return null
> end filter
> The plugin reads the cache size, jdbc driver, connection string, table to use and domain field from nutch-site.xml
