    Works with **any HTTP method** (`GET`, `POST`, etc.), which makes it compatible
    with protocols like MCP that stream SSE over `POST`.

    The actual encoding logic lives in the FastAPI routing layer. This class
    serves mainly as a marker and sets the correct `Content-Type`.

In addition, there can be several *static* subroutes used to differentiate between different handlers of the same ID.
A subroute on a client must match a subroute on the server. So routes cannot be used for dynamic routing, unlike HTTP.

Handlers should remain backwards compatible. If a breaking API change is required, a new handler ID should be created.

## Setup & Configuration

    val socketAddress = InetSocketAddress.createUnresolved("myproxy", 8008)
    proxySelector.proxies.add(Proxy(Proxy.Type.HTTP, socketAddress))

    // Define two host names for the DNS routing of fake proxy servers
    val proxyServer1 = InetAddress.getByAddress("proxyServer1", byteArrayOf(127, 0, 0, 2))
    val proxyServer2 = InetAddress.getByAddress("proxyServer2", byteArrayOf(127, 0, 0, 3))
