## SSE mit POST { #sse-with-post }

SSE funktioniert mit **jedem HTTP-Method**, nicht nur mit `GET`.

Das ist nützlich für Protokolle wie [MCP](https://modelcontextprotocol.io), die SSE über `POST` streamen:

`CORSMiddleware` отвечает на два типа HTTP-запросов...

### CORS-запросы с предварительной проверкой { #cors-preflight-requests }

Это любые `OPTIONS`-запросы с заголовками `Origin` и `Access-Control-Request-Method`.

В этом случае middleware перехватит входящий запрос и отправит соответствующие CORS-заголовки в ответе, а также ответ `200` или `400` в информационных целях.

### Простые запросы { #simple-requests }
