Questions over examples for Variants

[tunetheweb]

I'm confused with the examples in https://httpwg.org/http-extensions/draft-ietf-httpbis-variants.html

GET /foo HTTP/1.1
Host: www.example.com
Accept-Language: en;q=0.5, fr;q=1.0 

My (limited!) understand of this is it means "I'd prefer French, but next preference is English if French is not available".

The example response is this:

HTTP/1.1 200 OK
Content-Type: text/html
Content-Language: en
Vary: Accept-Language
Transfer-Encoding: chunked

[French content]

Why is the Content-Language: en but the content in French? The only way this would make sense is if it was French content aimed at English speakers (e.g. a French course for English speakers) but that's a bit of an edge case so presume that is that the intention here? Shouldn't the Content-Language either be fr, or the Content be in English so they match? It looks like it was in previous drafts but then it was flipped around, so not sure if this got missed or if I'm completely missing the point.

Moving on we have the new example using the same request:

GET /foo HTTP/1.1
Host: www.example.com
Accept-Language: en;q=0.5, fr;q=1.0

and the new response with the additional proposed syntax:

HTTP/1.1 200 OK
Content-Type: text/html
Content-Language: en
Vary: Accept-Language
Variants: Accept-Language;de;en;jp
Variant-Key: en
Transfer-Encoding: chunked

[French content]

Here it says there are German, English and Japanese versions (and no French version), and I've decided to send you the English version, and then it gives French content? Again should this be [English content]?

You're correct. I fixed this a while back but forgot to update this bug; please have a look again and if you still see an issue, please comment here.

Thanks!
