Recommendations for setting cookies behind load balancer that terminates SSL
We have an architecture where secure requests go through an SSL-terminating load balancer. That request is then sent to nginx, and then hits the node js application. Within, the node js application, we are using Koa (ctx.cookies) to set a secure cookie, which then crashes our server with `Error: Cannot send secure cookie over unencrypted connection`. Is it possible to set a secure cookie within this architecture, or are we stuck with setting non-secure cookies?

I'm setting `app.proxy` to `true` but am still seeing issues when trying to set a secure cookie.
