* 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.

(cache_url_handler): Add more debug output. Restore original request
headers when CACHE_SAVE filter isn't added to fix up after the request.

* modules/cache/mod_cache.c
(cache_save_filter): Instead of unconditionally returning a 304 when
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.

* modules/cache/mod_cache.c: If we add a new Expires value, tell our client;
merge in headers properly (or better than before) so that we can update the

Add preserve_orig flag to ap_cache_accept_headers to allow updating of fields.
