# Buffering

SSE requires **unbuffered** responses. Ensure your HTTP client and any intermediary proxies do not buffer the response body:

* **Nginx:** Set `proxy_buffering off;` or the API already sends `X-Accel-Buffering: no`
* **CloudFront / CDN:** Disable response buffering for SSE endpoints
* **HTTP Client:** Use streaming mode (not buffered reads)
