OK What about this, at the expense of an additional GET :
<VirtualHost www.foo.bar>
RewriteCond %{HTTP_COOKIE} MYCOOKIE
RewriteRule ^(.*)$ http://cache.foo.bar$1 [P]
ProxyPassReverse / http://cache.foo.bar/
ProxyPass / http://backend.foo.bar/
ProxyPassReverse / http://backend.foo.bar/
</VirtualHost>
<VirtualHost cache.foo.bar>
ProxyPass / http://backend.foo.bar/
ProxyPassReverse / http://backend.foo.bar/
CacheEnable /
</VirtualHost>

I don't think that will work reliably. Although it will prevent requests with the cookie set from being cached, it will not prevent responses for non-cookie users being served to cookie users. This is because mod_cache runs as a quick-handler, before mod_rewrite has had a chance to run.
