Forward Proxy Advanced

The Forward Proxy plugin allows Kong to connect to intermediary transparent HTTP proxies, instead of directly to the upstream_url, when forwarding requests upstream. This is useful in environments where Kong sits in an organization’s internal network, the upstream API is available via the public internet, and the organization proxies all outbound traffic through a forward proxy server. Please note that this plugin can’t be used with an upstream. As a workaround for load balancing, configure the host field in service to a domain name so that you can use a DNS-based load balancing technique.

The plugin attempts to transparently replace upstream connections made by Kong core, sending the request instead to an intermediary forward proxy. Only transparent HTTP proxies are supported; TLS connections (via CONNECT) are not supported.
