Commonly assumed

Passing a stream or resource sink to a request that follows redirects writes only the final destination response body into the sink.

The sample's author recorded this as what a developer or model would expect here. The contract below is what actually ran.

Contract

• assert a stream sink passed during redirected requests accumulates both intermediate redirect bodies and final response body instead of only the destination body
• assert the returned PSR-7 response body contains only the final destination body while the sink contains all hops concatenated
• assert http_errors throws a ClientException on 4xx responses but leaves the error body written to the sink stream
• assert on_headers callback is invoked on every intermediate redirect response before location following
• assert throwing inside on_headers aborts the request as ResponseException and prevents any bytes from writing to the sink
• assert same-origin redirects preserve Authorization headers while scheme downgrade redirects to http on the same host strip Authorization
