Those are sizes from chunked encoding.

I am trying to add some low level tracing to a client app to validate the responses coming from a SaaS platform.

When I use either http's resp.Write(os.Stderr) or httputil.DumpResponse(resp, true) I see a hex content length immediately before the body and a literal "0" on a line after,

i.e. using a local copy of the doc example for DumpResponse() but with a real URL and outputting "string(dump)" instead of quotes bytes) to a local server I get (HTML between open/close removed for brevity):

The "d2" is the content length and the "0" is extra. Compared against Postman and curl on the command line, to be sure.

Is this expected by undocumented or have I missed something please?
