> On a stale cache entry a HEAD gets tunneled to the origin, but when a 200 comes back HttpTransact::handle_cache_operation_on_forward_server_response(State* s)
> deletes the cache entry, it seems like it should just ignore it (or check ETag/Last-Modified and maybe delete if those don't match, but not unconditionally.)
> I am seeing this with 4.2.X with a plugin fiddling with stuff, but the code looks the same in trunk, line 4318 looks like the problem line.
