Hi guys,<div><br></div><div>I configured nginx to be used as HTTP reverse proxy on Amazon EC2, the back end servers are somewhere on the Internet. The problem I'm facing is that nginx sometimes returns HTTP 200 with Content-Length: 0 for a while, and the duration is approximately 5 minutes( when "proxy_cache_valid 200 301 5m;" is configured in server section), or 10 minutes(when "proxy_cache_valid 200 301 10m;" is configured in server section). I really have no idea why this happens. Any information is appreciated.</div>
<div><br></div><div>I tried to analyze the network packet flows, it seems nginx didn't contact the upstream servers in these situations.</div><div>The curl log is:</div><div><div>localhost:DX dennis$ curl -I $aptokyo002</div>
