x-relay-target	Yes	-	URL target yang ingin di-proxy
x-relay-path	No	/	Path yang ditambahkan ke target

Contoh

curl -H "x-relay-target: https://jsonplaceholder.typicode.com/posts/1" https://proxy-bun.vercel.app/

curl -H "x-relay-target: https://api.example.com" \
     -H "x-relay-path: /v1/users" \
     https://proxy-bun.vercel.app/

HTTP Methods

Mendukung semua HTTP methods:

• GET, HEAD - tanpa body
• POST, PUT, PATCH, DELETE - dengan body

Header Handling

Relay headers yang di-strip sebelum forwarded:

• x-relay-target

• host

Headers lain tetap di-pass.

Error Handling

{
  "error": "Missing x-relay-target header"
}

HTTP 400 jika x-relay-target tidak ada.
