Summary: The Accept-Language header that webkit sends is not properly dealing with locales (e.g.
brazilian portuguese), and it only sends one language, even if you have defined multiple ordered
languages in your system preferences.
* Open up System Preferences -> International -> Language
* Load <http://www.gmdc.org/publicapp/snoop.serv?testParm1=testVal1&testParm2=testVal2> (or
any other web page showing you the HTTP headers
Now move the following langauges to the top of the list in System Prefs, and reload the page, noticing
the value of the Accept-language parameter.
For instance (view in a monspaced font):
Topmost Locale Expected Actual
-------------- -------- ------
British English en-gb en
Australian English en-au en-us
Canadian English (eh?) en-ca en-us
Portuguese pt pt-pt
Brazilian Portuguese pt-br pt-pt
German de de-de
Swiss German de-ch de-de
Canadian French fr-ca fr-fr
Swiss French fr-ch fr-fr
The other issue is that according to <http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html>, you
can specify multiple languages that your browser accepts; it seems that WebKit should take more than
just the topmost language in AppleLanguages into account.
