Ok, this one looks ok. Rabbit send data from cache.

Ok, IE sends a conditional request.
Section 14.26 in rfc 2616 gives more info.
Basically what this means is that IE has a cached version of that image and
say "I want this image if it does not have any of the identites given 
(only gives
one etag in this case)".
RabbIT most probably answears with a 304 Not Modified as the rfc say it 
should.
In that response RabbIT sends a full header with lots of cache information.
It could be that rabbit say that the image is only 4711 bytes long and 
IE think
that it should be 50 000 bytes...
I need the response rabbit sends here to be sure. (Dang its one of the 
cases where
the response does not go through the filters, so we do not see it here 
as we
would like).

The other answear would be a normal return 200 ok, with full data.

Can you setup ethereal to trace a request that is bad?
I do not have IE installed (well no windows so its kind of hard for me 
to test this).

Same as above.
The rest of the "bad response" are the same type of thing.

No cache validation, only a normal request.

And requests come back like they ought to....
