Agreed. I don't see any situations where this should happen.

It can be any of the following

   - Client sending an IMS query resulting in a 304 response

   - Client sending a range request, only asking for a piece of the object

   - Client aborts the request before the whole response have been sent

Squid adds to the Vary header, and strips hop-by-hop headers as required
by the HTTP protocol. In addition you have optional anonymization
functions which strips unwanted http headers.
