---------------------------------------------
Summary: Regression causing issues with cross-site redirects
Key: HTTPCLIENT-1193
URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1193
Project: HttpComponents HttpClient
Issue Type: Bug
Components: HttpClient
Affects Versions: 4.2 Final
Reporter: Magnus Gustavsson
The release version of HttpClient 4.2 introduces a regression with cross-site
redirects that didn't exist previously.
According to Oleg Kalnichevski in HTTPCLIENT-1185: "There is unfortunately a
bug in the BasicClientConnectionManager introduced in 4.2 causing issues with
cross-site redirects."
For example, the following code
import java.io.IOException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;
public class BadRequest {
public static void main(String[] args) {
try {
HttpClient httpclient = new DefaultHttpClient();
HttpGet httpget = new
HttpGet("http://www.edu.mah.se/KK3231/syllabus/";);
System.out.println(httpclient.execute(httpget).getStatusLine().getStatusCode());
} catch (IOException e) {
e.printStackTrace();
}
}
}
raises an exception as follows:
