26.430New setting to limit total time for reading HTTP request headers, protecting against slowloris attacks.

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.
