Fields

max_body: String

e.g. “2MiB”. Requests with a larger body are rejected with 413.

max_response_body: String

Cap on the upstream response body EdgeGuard buffers, e.g. “16MiB”. “0” disables the cap (unbounded). Protects against an upstream OOM-ing the proxy; raise it if you proxy large downloads.

upstream_timeout: String

Max time to wait for the upstream response and to read its body, e.g. “30s”, “500ms”, “2m”. “0” disables the timeout. Bounds a stalled upstream so it can’t pin a handler task indefinitely; on elapse the proxy returns 504.

max_header_bytes: String

Cap on the total size of incoming request headers (sum of name + value bytes), e.g. “32KiB”. “0” disables the cap (default). Requests over the limit get 431. This is a policy limit enforced by EdgeGuard on top of hyper’s own transport-level header cap.

allow_methods: Vec<String>

Allowed HTTP methods; empty list means allow all.

stream_passthrough: bool

Stream (don’t buffer) responses whose Content-Type is text/event-stream. Off by default: the proxy normally buffers the whole upstream body so it can cap size (max_response_body) and account exact egress bytes. That buffering defeats Server-Sent Events / chunked streaming — the client only sees the body once the upstream finishes. Turn this on to forward SSE responses frame-by-frame as they arrive (preserving time-to-first-byte). When a response is streamed this way the max_response_body cap and the body-read deadline don’t apply (the connect/first-byte upstream_timeout still does); egress bytes are tallied as frames flow. Non-SSE responses are unaffected.
