Subject [jira] [Commented] (HTTPCLIENT-1309) UnknownHostException if DefaultHttpClient asked to handle HttpRequest whose host name includes a port
Date Wed, 30 Jan 2013 00:35:12 GMT

    [ https://issues.apache.org/jira/browse/HTTPCLIENT-1309?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13566010#comment-13566010
] 

Ian Blavins commented on HTTPCLIENT-1309:
-----------------------------------------

G'day

It looks like it might be a mismatch between what I said the target is and what I put in the
request. In your snippet of code try replacing:

   HttpHost target = new HttpHost("127.0.0.1", 8080)

with 

   HttpHost target = new HttpHost("127.0.0.1")

so that the target and request no longer agree.

>          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

> If a DefaultHttpClient is passed, in its .execute(target, request, context) method call,
an HttpRequest whose host name field contains a port suffix (eg 192.168.0.102:8080) then SystemDefaultDnsResolver
will try to resolve the host name plus port and gets an UnknownHostException: java.net.UnknownHostException:
192.168.0.102:8080.
> 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)
