I have question regarding AWS ALB. Does anybody knows if it is possible to modify (specifically ADD) custom headers to requests? Something like proxy_set_header in nginx http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_set_header
ALB and ELB set some standard headers:
X-Forwarded-Port: (see here).
I don't think you can set your own headers. What do you need it for?
