@Scottmitch @nmittler please have a look guys :)
 I wonder if `HttpConversionUtil` should just group all multi-valued headers into single entries (i.e. not treat `Cookie` as special here). It wouldn't be invalid and I suspect would perform better end-to-end. 

@Scottmitch WDYT?
 @nmittler +1
 @nmittler - As far as I can tell, that won't work.  What is true for one header is not necessarily true for others. Specifically I can think of the `Set-Cookie` header.  In this case (depending which version/browser you use) sending each cookie in a separate `Set-Cookie` header is actually the correct thing to do (log into or out of facebook to see an example of this).
 Yup, looking at https://tools.ietf.org/html/rfc7230#section-3.2.2 ...

`Set-Cooke` is the exception.  It also sounds for Netty to function as a proxy, it should not merge headers.

And as described in http://tools.ietf.org/html/rfc6265#section-5.4: `the user agent MUST NOT attach more than one Cookie header field`.

@blucas Are you saying that Chrome is sending multiple `Cookie` headers, or that it's sending a multi-valued `Cookie` header that Netty is then splitting into separate headers? The former would appear to be a chrome bug.
 +1 for not merging headers :smiley: 

@nmittler I haven't checked that yet. My assumption is that it is a Netty related issue, as Firefox is also affected by this.  I will check now and get back to you
 Ok, so I still don't know if it is the browser's or netty's (possibly twitter hpack's) fault.  All I can tell you is
- Both Firefox and Chrome exhibit the issue
- Single call to [addFragment](https://github.com/netty/netty/blob/master/codec-http2/src/main/java/io/netty/handler/codec/http2/DefaultHttp2FrameReader.java#L669) which has `endOfHeaders` set to true.

Maybe @Scottmitch could shed some light on this one?

BTW, looking at chrome://net-internals for the request generated this stack:

Chrome did the `[118 bytes were stripped]` not me.
 @blucas - Can you post your server code somewhere (or some reduced set of it)? I just modified the example http2 helloworld server and client to both use the HTTP/1.x translation layer and added a cookie from the client (`request.headers().add(HttpHeaderNames.COOKIE, "foo1, foo2");`) and this is what I see on the server side:

```
DefaultFullHttpRequest(decodeResult: success, version: HTTP/1.1, content: UnpooledUnsafeHeapByteBuf(ridx: 0, widx: 0, cap: 0))
GET /whatever HTTP/1.1
x-http2-scheme: http
host: 127.0.0.1:8080
accept-encoding: gzip
accept-encoding: deflate
cookie: foo1, foo2
x-http2-stream-id: 3
content-length: 0
```

It looks like CSV headers are preserved (`cookie`), and multiple headers as different entries (`accept-encoding`) are preserved.  Are you thinking we should always force everything to be a single CSV separated value unless otherwise prohibited from doing this by the spec?
 @Scottmitch - I don't have a reproducer handy for you to test with, but all you need to do is make your HTTP/2 client send multiple `cookie` headers to your netty HTTP/2 -> HTTP/1.x translation server.

> Are you thinking we should always force everything to be a single CSV separated value unless otherwise prohibited from doing this by the spec?

No. We shouldn't force everything to use single CSV.

I took a look at the HTTP/2 spec, and finally think I've found what I'm trying to explain. 

> To allow for better compression efficiency, the Cookie header field MAY be split into separate header fields, each with one or more cookie-pairs.

So, according to the [spec](https://http2.github.io/http2-spec/#CompressCookie), it is perfectly valid for a HTTP/2 client to send multiple `cookie` headers (thus Firefox and Chrome are complying with the spec).  //cc @nmittler - I believe this answers your question.

> If there are multiple Cookie header fields after decompression, these MUST be concatenated into a single octet string using the two-octet delimiter of 0x3B, 0x20 (the ASCII string "; ") before being passed into a non-HTTP/2 context, such as an HTTP/1.1 connection, or a generic HTTP server application.

So I interpret that as Netty's `HttpConversionUtil.Http2ToHttpHeaderTranslator` should be responsible for concatenating one or more HTTP/2 `cookie` headers into a single HTTP/1.x `Cookie` header.

```
// Example 1 - Client sends multiple single value HTTP/2 cookie headers
cookie: a=b
cookie: c=d
cookie: e=f

// Netty should translate that to a single HTTP/1.x Cookie header
cookie: a=b; c=d; e=f

// Example 2 - Client sends single and multi-value HTTP/2 cookie headers
cookie: a=b; c=d
cookie: e=f

// Netty should translate that to a single HTTP/1.x Cookie header
cookie: a=b; c=d; e=f
```

I hope that makes more sense :smiley: 
 @Scottmitch - gentle ping :)
 @Scottmitch ^^ 
 @blucas - Sorry for the delay and thank you for the reference to the specification. I will submit a PR soon.

yikes ... was this missing? :)
 Not new code, but why does the `if` statement above check for the value of `trailers`? Seems like checking the name equals `te` is sufficient, no?
 final?
 yikes :)
 Are we guaranteed that we need to skip exactly 2 characters?
 Maybe check for the exceptional case first? Then you don't need the else.
 Yes sir it was :(

We were previously using all `AsciiString` in tests apparently so the value comparisons using POJO `equals` was sufficient.
 It is defined/declared in an interface, so it is final by definition.

> /Users/scott_mitchell/git/netty/common/src/main/java/io/netty/util/ByteProcessor.java:126:5: Redundant 'final' modifier.
 https://tools.ietf.org/html/rfc7540#section-8.1.2.2

> The only exception to this is the TE header field, which MAY be
>    present in an HTTP/2 request; when it is, it MUST NOT contain any
>    value other than "trailers".
 Yip :frowning: A few of the new unit tests now test this.
 Right, I'm just not sure why this logic cares about the value.  It would we would only care if we were going to enforce that requirement (i.e. throw if the value is NOT `trailers`).
 I believe so. Let me add a reference to the cookie RFC to clarify.

https://tools.ietf.org/html/rfc6265#section-4.2.1

> cookie-header = "Cookie:" OWS cookie-string OWS
>    cookie-string = cookie-pair *( ";" SP cookie-pair )

https://tools.ietf.org/html/rfc6265#section-4.1.1

> cookie-pair       = cookie-name "=" cookie-value
 ah right ... didn't notice that this was an interface. Sorry for the noise :)
 done
 I guess we are enforcing it by not including it in the resulting headers, but we can throw to be more explicit if you prefer.
 I think throwing is probably the right thing to do ... otherwise, AFAICT we're silently dropping this header on the floor. WDYT?
 done.

HttpConversionUtil - Incorrect conversion of Cookie header
Netty Version: master (latest snapshot: a6816bd59ef2923d82af5b7a7f3b722507a56a3a)

The browser (I used Chrome 46.0.2490.80 for testing) sent an HTTP/2 request containing multiple cookies to a netty service, the `HttpConversionUtil` generated multiple `Cookie` header entries in the HTTP/1.x request. According to [one stackoverflow post](http://stackoverflow.com/questions/16305814/are-multiple-cookie-headers-allowed-in-an-http-request), this is incorrect behaviour. The `HttpConversionUtil` should generate a single `Cookie` header containing all cookie values.

// cc @Scottmitch @nmittler - I could provide a patch, but I'm not too sure the best approach to take. Considerations about how to extract the cookies, and reformat them into a single header have to be made. If you could give me some tips, I might be able to come up with a PR.
