Apache Commons HTTPClient 3.x leaving connections open

Answer 1

You need to call HttpMethodBase#releaseConnection(). If you return a InputStream to be used later, a simple way is to wrap it by a anonymous FilterInputStream overwriting close():

final HttpMethodBase method = ...;
return new FilterInputStream(method.getResponseBodyAsStream())
{
  public void close() throws IOException
  {
    try {
      super.close();
    } finally {
      method.releaseConnection();
    }
  }
};
