Agentgateway as a reverse proxy

[artberger]

request from Lin during community meeting 3/19/2026

Document how we use agentgateway as a reverse proxy

• things like proxy API requests to a particular service inside the cluster
• for this path, set these headers, pass it to the service
• John has a pretty in-depth blog about using nginx for a local proxy over docker: https://blog.howardjohn.info/posts/agentgateway-at-home/
• This use case is common for demos
