http_headers_progress_interval_ms
Do not send HTTP headers X-ClickHouse-Progress more frequently than at each specified interval.
http_headers_read_timeout
Maximum time in seconds to read all HTTP request headers. This is a total deadline for the entire header parsing phase, not a per-read timeout. Protects against slowloris-style attacks where a client trickles header data slowly to hold connections open.
