non proxied and reverse proxied requests.
We need to handle both cases in the same manner as for the reverse proxy
case we have the following situation:
If a cached entry is looked up by mod_cache's quick handler r->proxyreq
is still unset in the reverse proxy case as it only gets set in the
translate name hook (either by ProxyPass or mod_rewrite) which is run
after the quick handler hook. This is different to the forward proxy
case where it gets set before the quick handler is run (in the
post_read_request hook).
If a cache entry is created by the CACHE_SAVE filter we always have
r->proxyreq set correctly.
So we must ensure that in the reverse proxy case we use the same code
path and using the canonical name seems to be the right thing to do
in the reverse proxy case.

* Add r->uri to the debug messages in the quick handler; makes debugging
easier.
* Always reset headers_in for lookup's, some modules make subrequests
and then rewrite the url. Having a conditional request at this point
is not what they expect (nor reasonable for them to handle).
* Don't store a per-request config on lookups; for the same reason.
* Return DECLINED when in lookup mode and ap_meets_conditions() indicated
we have the content but don't know if it's fresh or not. We have no idea
whether the backend will have a 404, a 304 or any other kind of a
response - so we have to assume we cannot handle the request.
* remove the unused "url" argument from the cache_create_entity() function
* Whitespace/comment fixups in mod_cache.h

Remove entities from the cache when re-validation receives a 404 or other
content-no-longer-present error.

the original request was conditional and we issued a cache revalidating
request, handle the request as if it came in while our cache was
still valid.
* modules/cache/cache_storage.c
(cache_select_url): Strip off the conditional headers from the original
request, prior to adding our own for the purpose of revalidating our
cached response.
