[jira] [Commented] (HTTPCLIENT-1744) code treats domain names or hostnames case sensitive. This will cause verification to fail because FQDN are case insensitive.

    [ https://issues.apache.org/jira/browse/HTTPCLIENT-1744?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15292017#comment-15292017 ]

Are you sure this is a bug? #matchDomainRoot method is package private. Callers of this method are expected to pass normalized host and domainRoot as input.

> in class DefaultHostnameVerifier in the method  static boolean matchDomainRoot(final String host, final String domainRoot); and maybe else where the code treats domain names or hostnames case sensitive. This will cause verification to fail because FQDN are case insensitive.
> host.endsWith(domainRoot)
