RFC 10036 defines "Incremental" HTTP header to stop intermediaries from buffering complete messages
↗
RFC 10036 specifies a new "Incremental" HTTP header field that instructs HTTP intermediaries to forward messages incrementally rather than buffering the entire message before forwarding.
Applications that depend on incremental delivery, such as Server-Sent Events and bidirectional HTTP exchanges, break when an intermediary buffers a complete message before forwarding it. This header gives senders an explicit signal to request streaming behavior, but intermediaries that do not recognize the field will ignore it entirely.

The "Incremental" header is a structured field of type Item accepting only Boolean values, where ?1 requests incremental forwarding and ?0 signals default buffering behavior.
The header applies to each HTTP message individually, so both request and response must carry it if both directions need incremental delivery.
Intermediaries unaware of the field will not change their behavior, and intermediaries that do support it may choose to reject the request instead of complying.
