I have a serious issue. It seems that if something happens during a
proxy request after mod_http_proxy starts reading from the backend
server, no error is reported. (IE, see what happens when
ap_pass_brigade returns non success). The problem is that this
"partial page" may be cached because r->status is a cacheable code,
but the response is actually "broken." The result is that the broken
version may be cached and served again and again.
Should we break RFC (maybe) and change r->status to 503 (for example)
so cache can check letter.
Note: this is using our internal mod_cache, but looks like the issue
would be the same in stock mod_cache.

I don't think its breaking the RFC to not-cache partial pages.
