Interface IResponse

public interface IResponse

IWDResponse represents the response to a HTTP request, as performed with an IWDRequest.

Whether the IWDResponse keeps a Document is influenced by two factors:

1. when the IWDRequest indicated that a response document is expected
2. when the response carried a 207 status code with content type text/xml

However the document may still be null due to missing response body, etc.

Whether the IWDResponse keeps a InputStream is influenced mainly by the indication in the IWDRequest, namely if the client indicates that he would like to get the response as a InputStream.
