Nginx redirect to https need page refresh -

i have through tutorials on internet redirect http -> https. have got worked out, doesn't work 100% correctly

my environment on centos 6.5 (right set in 1 server in development mode):

1.) 1 nginx (v 1.8.0) load balancer (running on port 443 , 80)

2.) 2 node.js express.js web servers (running on port 3000)

3.) 1 mongodb database (running on port 27017)

what got far

i trying redirect user http https on load balancer.

i want node.js render "hello nodes" ( set )

what went wrong

when enter https://my.domain.com , render "hello nodes" ( work correctly )

but when enter http://my.domain.com , render "welcome nginx"; however, when refresh browser render "hello nodes"

it seems have refresh browser in order redirected https.

i want redirect https right after enter http://my.domain.com without needs of page refresh

thank :)
