Subject [jira] [Commented] (HTTPCLIENT-1309) UnknownHostException if DefaultHttpClient asked to handle HttpRequest whose host name includes a port
Date Tue, 29 Jan 2013 23:15:13 GMT

    [ https://issues.apache.org/jira/browse/HTTPCLIENT-1309?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13565940#comment-13565940

Oleg Kalnichevski commented on HTTPCLIENT-1309:

Works for me with 4.2.1 as well without any modifications to the SystemDefaultDnsResolver.

Please upgrade to 4.2.3 and try to reproduce the problem with a test case.

>             Project: HttpComponents HttpClient
>          Issue Type: Bug
>          Components: HttpConn
>    Affects Versions: 4.2.3
>         Environment: Mac OS X 10.6.8  HttpClient 4.2.1 - field above won't let me put
in 4.2.1
>            Reporter: Ian Blavins
>            Priority: Minor
> If a DefaultHttpClient is passed, in its .execute(target, request, context) method call,
an HttpRequest whose host name field contains a port suffix (eg then SystemDefaultDnsResolver
will try to resolve the host name plus port and gets an UnknownHostException: java.net.UnknownHostException:
> There appears to be a work around and that is to download the source of SystemDefaultDnsResolver,
make the obvious change to remove any port and then rebuild httpclient-4.2.1.jar. (There is
probably an easier way to present the revised SystemDefaultDnsResolver since its intended
to be replaced by the user developer but I haven't discovered it)
