Only in domain / authentication

[Diego Bonesso]

Hello, I have two questions? I'm using nutch 2.2. I put two urls in
seed.txt . In  dir /conf in nutch-site.xml, I create a property
db.ignore.external.links with value true. First question my job should stay
only in two urls domains? In the second url I have to authenticate , how i
can configure this? The url auth is something like
http://www.domain.com/login. Thanks a lot.
