If this is the case then it is a server bug! The Content-Length header
should be sent whenever possible in a full response, and it should certainly
not have anything to do with the media type in which the object is rendered.
I can imagine that the problems can be due to server side includes in the
documents or dynamic documents generated by scripts.
