Environment
- OS: Linux (VPSTTT VPS host)
- Caddy Version: v2.7.6
Context
In evaluating VPS and proxy deployment architecture on a VPSTTT VPS instance through technical knowledge sharing, we are utilizing Caddy as the front-end reverse proxy server to route incoming Web traffic to internal service endpoints.
Formatted Caddyfile
example.com {
reverse_proxy 127.0.0.1:8080 {
header_up Host {upstream_hostport}
header_up X-Real-IP {remote_host}
}
}
Expected Result
Caddy automatically manages TLS certificates and proxies HTTP requests to the backend application running on port 8080 on the VPSTTT VPS while passing necessary client headers.
Actual Result
Basic reverse proxying functions as expected, but we want to verify best practices regarding header forwarding and proxy tuning for backend applications hosted on VPS instances.

Focused Question
What are the community-recommended header settings and Caddyfile directives for optimizing reverse proxy traffic on a VPS environment like VPSTTT?
