# Echoes back details of the incoming request for any HTTP method.

`HEAD` `/anything`

Operation ID: `anything_handler`

This endpoint is useful for debugging and understanding how requests are processed. It reflects the method, path, query parameters, headers, and body of the request. # Responses: - `200 OK`: Successfully echoed the request details as a JSON object. Note: While this handler is registered for `/anything` and `/anything/*path`, the OpenAPI documentation for `/anything/*path` is handled by `anything_path_handler` due to current limitations in `utoipa` with wildcard path parameters in a single handler.

## Query parameters

- `connection` (string, optional) - Set to `close` to force a `Connection: close` response and hang up the connection afterward (HTTP/1.1 only; ignored over HTTP/2)

## Request body (required)

Content types: `application/octet-stream`

## Responses

- `200` - Echoes request details (includes a `tls` object over HTTPS; a `connection` field when `?connection=close` is set)
