Upstream: even better handling of invalid headers in cache files. When parsing of headers in a cache file fails, already parsed headers need to be cleared, and protocol state needs to be reinitialized. To do so, u->request_sent is now set to ensure ngx_http_upstream_reinit() will be called. This change complements improvements in 46ddff109e72.
