Subject [jira] Created: (HTTPCLIENT-1039) AbstractHttpClient.determineTarget does not recognize target host correctly

AbstractHttpClient.determineTarget does not recognize target host correctly

                 Key: HTTPCLIENT-1039
                 URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1039
             Project: HttpComponents HttpClient
          Issue Type: Bug
          Components: HttpClient
    Affects Versions: 4.1 Beta1
            Reporter: Marco Rocci

I am trying to execute an HttpGet with the following URI:

This leads to ???

Going through the internal code, the problem seems to be in the AbstractHttpClient.determineTarget
            String ssp = requestURI.getSchemeSpecificPart();
            ssp = ssp.substring(2, ssp.length()); //remove "//" prefix
            int end = ssp.indexOf(':') > 0 ? ssp.indexOf(':') :
                    ssp.indexOf('/') > 0 ? ssp.indexOf('/') :
                    ssp.indexOf('?') > 0 ? ssp.indexOf('?') : ssp.length();
            String host = ssp.substring(0, end);

This code sets the target host to "www.foo.foo/doSomething.html?url=http" instead of "www.foo.foo".
This obviously breaks the execution not far down the line... DefaultClientConnectionOperator.resolveHostname
throws an UnknownHostException.

FWIW the AbstractHttpClient.determineTarget method actually has access to the request URI
object, which correctly states that the host is "www.foo.foo".

So why does it try to extract the host from the scheme specific part anyway?

I hope this is useful... and if there is any workaround please let me know, as I'm stuck on
this one.
