setting response headers in AtomFeedProvider

[Paul Wilton]

Hi Sergey,
I was planning on setting a response header (Last-Modified, expires,
cache-control etc) in an extended AtomFeedProvider based on the Feed
updated data, 

for example:

public class AtomFeedProvider extends
org.apache.cxf.jaxrs.provider.AtomFeedProvider {

    @Override
    public void writeTo(Feed feed, Class<?> clazz, Type type,
Annotation[] a, MediaType mt, MultivaluedMap<String, Object> headers,
OutputStream os) throws IOException {
        headers.add("Last-Modified", feed.getUpdated());
        super.writeTo(feed, clazz, type, a, mt, headers, os);
    }
}


However, in the source
org.apache.cxf.jaxrs.provider.AtomFeedProvider.writeTo() method the
headers are ignored (lost).
Is this the correct approach I am taking to add headers, or is this a
bug, or is there a better way ?

Thanks
Paul
