Hello Fabian,

Best regards,

> I've noticed (Restlet 2.0snapshot from 2010-02-19 IIRC) that there's
> no @Head annotation to handle HEAD requests. The method annotated with
> @Get is handling HEAD also. A priori this makes some sense because one
> expects to get the same answer for HEAD and GET, except that HEAD has
> just metadata (in the HTTP headers) while GET has both the metadata
> and a body with the representation of the resource in question.

> Look at this example, code:

> getLogger().info("-*-*-*-*-*-*-*-*-DBG: METADATA: " + cmd.toString());
> Representation rep = new EmptyRepresentation();
> rep.setModificationDate(cmd.getLastModif().getTime());
> rep.setSize(cmd.getSize());
> rep.setMediaType(new MediaType(cmd.getMimeType()));
> return rep;

> It basically creates an empty representation (no Content-Type header,
> Length header fixed to 0) and then tries to set the "correct" metadata
> (Content-Type, Length and Date are the ones I need properly set) by
> issuing standard API calls as suggested by both the Restlet engine and
> the docs at
