You can't turn it on and off within a virtual host - it's either on or
off, end of story.
I have encountered this and worked around it by using a second virtual
server which does preserve the host name, called by the first which
doesn't but it's not pretty and I wouldn't recommend it unless strictly
necessary.
It would be nice to be able to explicitly set the Host: header but that
appears to be overwritten when the request is proxied.
HTH,
Neil.
