Hi All,
I am struggling to get keepalives to work on Nginx, I believe I have
added the necessary configuration. Can you take a look and suggest where
I may be going wrong or what I am missing?
We have a nginx server that sits in front of a varnish server which sits
in front of the back-end servers
http {
keepalive_timeout 120;
keepalive_requests 500;
upstream varnish_rand {
server 172.21.1.1:80;
keepalive 256;
}
server {
server_name www.abc.com
location / {
proxy_pass http://varnish_rand;
proxy_http_version 1.1;
}
}
You can see that the nginx server is using HTTP1.1 to communicate with
Varnish
*varnishtop -i RxProtocol *
list length 1
9.67 RxProtocol HTTP/1.1
However there nginx always send a "connection close"
*varnishtop -c -i RxHeader -I "Connection"*
list length 1
9.59 RxHeader Connection: close
Thanks in advance
Nick
