Interface HttpRequest

Optional request body (already serialised).

Hard cap on the response body size in bytes; the request aborts if exceeded.

Always "manual" from the engine: a transport must not follow redirects. The engine follows them itself and decides per hop whether the Authorization header (the base URL's userinfo) goes along (same origin only). A fetch-based transport passes it on: fetch(url, { redirect }).

Aborted when the engine's overall deadline (timeoutMs) passes. A transport should stop the request then (fetch(url, { signal })); the engine rejects at the deadline either way, and enforces maxResponseBytes on the body it gets back, so neither limit depends on the transport.

Per-request timeout in milliseconds.

Fully-qualified absolute URL.
