Configure HTTP output

Setting	Default	Effect/quirk
Host/URL	Empty	Tag-processed destination. Prevent untrusted data from choosing the host.
Send method	POST	HTTP method used to upload/send.
Form encoding	None	Body/form encoding mode. Match content type and receiver contract.
Content field name	file	Multipart file field; runtime falls back to file if blank.
Headers	Empty	Tag-processed custom headers. Avoid secrets in traces and ordinary configuration where dedicated auth exists.
Protocol version	HTTP/1.1	HTTP/1.0 or HTTP/1.1.
Handle redirects / Follow location	Selected / selected	Redirect handling is active through Handle redirects; Follow location appears persisted but unused in reviewed initialisation. Test final host and whether authentication/body is replayed.
Connect / read timeout	15 / 0	Network waits; a timeout does not prove the server rejected the request.

Test every configured method/encoding, exact headers/content type, empty/large/binary payloads, 2xx/4xx/5xx, redirect, TLS failures, proxy and ambiguous timeout. Use a request/business idempotency key where the receiver supports it and reconcile before retrying. A successful Flow registration is separate from this HTTP result and a successful HTTP result may still require business response validation. See Transport operations.
