The cache is using the rewritten URL.

Sequence is approximately

* Request accepted
* http_access Access controls
* URL rewriting, replacing Squid's idea of the URL
* http_access2 Access controls
* Cache lookup
* Forwarding on cache miss
* http_reply_access Reply access controls

Because of this using "url_rewrite_host_header off" can be a very bad
thing as it makes the requested URL sent to the web server differ from
the cache URL, and can easily bite you..
