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 which headers go along (caller headers and the base URL's credentials to the 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 it.

Timeout for the whole request, response body included, in milliseconds.

Fully-qualified absolute URL.
