net/http: error message says 'Request' instead of 'Response'

<pre>See example program: <a href="http://play.golang.org/p/E4noNAhYVv">http://play.golang.org/p/E4noNAhYVv</a>
During execution it prints (
Error writing response: http: Request.ContentLength=0 with Body length 11), while this
is obviously a response.

Looking at the code there are two places with that error.

Thanks.</pre>
