enable_streaming

Stream response bodies instead of buffering them in full.

Type
boolean
Default
true

When on, response bodies are streamed through the proxy as they arrive rather than fully buffered first. This keeps memory flat for large downloads and lets the client start receiving bytes immediately (lower time-to-first-byte).

Keep it on
Streaming is the right default for almost everyone — it bounds memory under big or slow responses. Buffering only helps niche cases where you must hold the whole body to transform it.
