Why would it? It's acting as a forwarder, not a rewriter. If we replaced
the host header then vhost mode generally wouldn't make much sense as
one would need one cache_peer per unique domain/hostname, not just one
per server..

2.6 didn't do this either. Neither did 2.5 when running in similar
httpd_accel_uses_host_header mode, but with 2.5 most forwarded requests
by rewriting the host part of the URL making a mess of things...

You mean something like forceddomain=name

                     use 'forceddomain=name' to forcibly set the Host header
                     of requests forwarded to this peer. Useful in accelerator
                     setups where the server (peer) expects a certain domain
                     name and using redirectors to feed this domain name
                     is not feasible.
