Proxy_pass via HTTP proxy

Server NGINX
1

Hi,

I am trying to configure my nginx instance so that it "proxy_pass"es to
another HTTPS server S.
However, in order to reach S, I need to go though an HTTP server P. This
means nginx would need to connect to P, issue a CONNECT request, and
then
tunnel the HTTPS request to S.
Is this supported? How to enable it?
I could not find mention in the documentation, and it is kind of hard to
search for :slight_smile:

Thank you,
Ludovico

just a try / not sure if it will work

  • when starting your nginx try to use a shellscript script that sets
    http_proxy / https_proxy:
    export http_proxy=http://server-ip:port/ ; i’m not sure it nginx has
    some
    options to use a 3rd proxy.

  • maybe you can use firewall-rules to do a simple portforwarding to your
    proxy P, but i’m not sure it will work (for intercepting http-traffic
    and
    using squid as a transparent proxy it works)

maybe https is an issue

regards,

mex

No.

Start coding :slight_smile:

Right now, nginx proxy_pass speaks http to a http server, or
http-over-ssl
to a https server. It doesn’t speak proxied-http to a http proxy
server. (Including the CONNECT method of proxied-http.)

So if you want that, you’ll need to look outside of current-nginx.
