Conditional GETs?

[Peter Lacey]

Hi,

I'm new to RESTlet and trying to create a resource that supports 
conditional gets (ETag, Not Modied).  So far I have the normal GET done, 
I can attach an ETag to the representation, I can see how to get the 
conditions from the client request, and I can see how to send back a 
304.  But for the life of me, I can't see how to send back a 304 _and_ 
the ETag.

To send the ETag I need to call setTag on a Representation.  But when 
I'm returning a 304, I don't have a Representation per se.  I've tried 
returning Variants and empty Representations (DomRepresentation in my 
case) from my resource's getRepresentation() method, but these attempts 
didn't pan out.  Nor has anything else I tried.

I would really appreciate it, if someone could explain or provide some 
sample code that shows how to do this.

Thanks,
Pete
