Ah.  So your problem is that you are trying to do a forward proxy,
whereas the [P] flag of mod_rewrite creates a reverse proxy (like the
ProxyPass directive).  I've never played much with forward proxies, so
I can't really help you here.  I don't know whether or not it is
possible to manipulate forward proxy requests with mod_rewrite.  I'd
tend to doubt it.  One idea would be to look at mod_cache and
mod_disk_cache rather than trying to role your own cache with
mod_rewrite.
