net/http: docs are wrong for multiple headers with same key #5979
Description
What steps will reproduce the problem? Run http://play.golang.org/p/SmkSnOoyAC locally. For reference, here is a sample response from that http server: HTTP/1.1 200 OK Custom: a Custom: b Content-Type: text/plain; charset=utf-8 Content-Length: 0 Date: Sun, 28 Jul 2013 21:02:11 GMT What is the expected output? The documentation for http.Response reads: "If the response had multiple headers with the same key, they will be concatenated, with comma delimiters. (Section 4.2 of RFC 2616 requires that multiple headers be semantically equivalent to a comma-delimited sequence.)" Given that, I'd expect to see "[a, b]" (a slice containing a single string, "a, b"). What do you see instead? "[a b]" (a slice containing two strings, "a" and "b"). Which compiler are you using (5g, 6g, 8g, gccgo)? 6g Which operating system are you using? OS X Which version are you using? (run 'go version') 1.1 Please provide any additional information below. It is not obvious to me whether the behavior or the documentation should be changed.
