> Key: VALIDATOR-248
> URL: https://issues.apache.org/jira/browse/VALIDATOR-248
> Project: Commons Validator
> Issue Type: Improvement
> Components: Routines
> Affects Versions: 1.3.1 Release
> Reporter: Sergey Nebolsin
> Fix For: 1.4

> Working on Grails we've discovered
> ([Grails-1692|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 (also see appendix G.3 paragraph 2, which says that explicitly).
> So, it would be good to add additional option (UrlValidator.ALLOW_LOCALHOST)
> which will control UrlValidator behavior on localhost URLs.
