Grecho is a simple asynchronous HTTP echo server written in Rust. It returns the request body, headers, and URI in the response, with support for customizing the response via internal headers.

Echo Request Body: Returns the same body as the request. Echo Request Headers: Returns the same headers as the request (excluding internal headers and the host header).

• Use internal.status-code to set a custom HTTP status code.
• Use internal.response-body to set a custom response body.

curl -X POST http://127.0.0.1:3000/example -d "Hello, World!" -H "Content-Type: text/plain"
curl -X POST http://127.0.0.1:3000/example -d "Hello, World!" -H "internal.status-code: 202"
curl -X POST http://127.0.0.1:3000/example -d "Hello, World!" -H "internal.response-body: Custom Body"
