Forward Proxy Advanced

The Forward Proxy Advanced plugin allows Kong Gateway to connect to intermediary transparent HTTP proxies, instead of directly to the upstream_url, when forwarding requests upstream.

This is useful in environments where the following is true:

1. Kong Gateway sits inside an organization’s internal network.
2. The upstream service is available via the public internet.
3. The organization proxies all outbound traffic through a forward proxy server.

The Forward Proxy Advanced plugin attempts to transparently replace upstream connections made by Kong Gateway, sending the request instead to an intermediary forward proxy.

Only transparent HTTP proxies are supported. TLS connections (via CONNECT) are not supported.

The Forward Proxy Advanced plugin can’t be used with an Upstream. As a workaround for load balancing, configure the host field in a Gateway Service to a domain name so that you can use a DNS-based load balancing technique.
