Description

Working on Grails we've discovered (http://jira.codehaus.org/browse/GRAILS-1692) that commons-validator's UrlValidator rejects URLs like "http://localhost:8080/tau_gwi_00/clif/cb/19". I looked at commons-validator sources and found that any URL which contains 'localhost' as it's hostname part will be rejected.

RFC-2396 (http://www.ietf.org/rfc/rfc2396.txt) accepts 'localhost' as a valid hostname (appendix G.3 paragraph 2 says that explicitly).

So, it would be good to have additional option (UrlValidator.ALLOW_LOCALHOST) which will control UrlValidator behavior on localhost URLs.
