Every second request goes to backend.

Hello,

I was just trying to experiment this module and I noticed that every second request goes to backend and every second request's response header says cache-status "EXPIRED" regardless of first request is MISS or EXPIRED. After that all subsequent requests get HIT until it actually expired according to time defined in header_filter_by_lua .

I have used the same code which is given in readme file. And proxy to same nginx server running at higher port.

I have also noticed that the cache file is being created on first request only which is expected behavior and if I remove this header_filter_by_lua code, each second request gets cache HIT.

Is this same code(which is given in readme) working in production servers or is there any change in readme?

Thanks,

Inizia dall’esempio del README, in particolare dalla configurazione header_filter_by_lua, e riproduci le richieste alternate verso il server nginx sottoposto a proxy. Confronta gli header cache-status e la creazione del cache-file con e senza questa configurazione. Il lavoro è completato quando si determina se l’esempio documentato causa le risposte alternate MISS o EXPIRED segnalate e si documenta o corregge il comportamento interessato.
