Subject [jira] [Created] (HTTPCLIENT-1309) UnknownHostException if DefaultHttpClient asked to handle HttpRequest whose host name includes a port
Date Tue, 29 Jan 2013 21:33:14 GMT
Ian Blavins created HTTPCLIENT-1309:
---------------------------------------

             Summary: UnknownHostException if DefaultHttpClient asked to handle HttpRequest
whose host name includes a port
                 Key: HTTPCLIENT-1309
                 URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1309
             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 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)
