Hi,
After experimenting with some parameters I used following configuration.
upstream appcluster { server host1.example.com:8080
max_fails=1 fail_timeout=1s; server host2.example.com:8080
max_fails=1 fail_timeout=1s; } server { listen *;
location / { proxy_pass
http://appcluster; proxy_next_upstream error timeout
http_404 http_500 http_502 http_503 http_504;
proxy_set_header X-Real-IP $remote_addr;
proxy_connect_timeout 2; proxy_send_timeout
2; proxy_read_timeout 5; }
}
The issue I am facing here is - with similar configuration in lighttpd response
time per request 0.3 seconds, where as with nginx it is around 2.5 seconds.
Can someone suggest me how to response time with nginx?
Thanks,Sandeep.

While looking at logs following message appeared:
