There is no such code in 0.8.47 either. Line 2951 in
ngx_http_request.c as of 0.8.47 looks like:

if (rc > 0 && (r->headers_out.status == 0 || r->connection->sent == 0)) {

and there is no "switch (r->upstream->cache_status)" statement in
the whole nginx source code (and never been, in all versions).
