            Bug ID: 280666
           Summary: Add Quirks for overriding the Accept-Language http
                    header for bestbuy.com
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
               URL: https://bestbuy.com/
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Misc.
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: karlcow at apple.com

When a user is trying to log in on the bestbuy.com website 
with Safari set as Japanese (Accept-Language: ja) or French-France (Accept-Language: fr-FR), 
the login is not working.

While at the same time this is working for Chrome and Firefox. 
Also some other languages will be accepted, even things such as French-Canada


Safari:

PASS Accept-Language: en-US,en;q=0.9
PASS Accept-Language: pt-BR,pt;q=0.9
PASS Accept-Language: fr-CA,fr;q=0.9

FAIL Accept-Language: fr-FR,fr;q=0.9
FAIL Accept-Language: ja


Firefox:
PASS Accept-Language: en-US,en;q=0.8,fr-FR;q=0.5,ja;q=0.3
PASS Accept-Language: fr-FR
PASS Accept-Language: ja



We also tried with Safari and overriding the User-Agent to be Firefox.

Not working:
* Accept-Language: ja
* User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:127.0) Gecko/20100101 Firefox/127.0


And it fails on Firefox with a Safari UA override.

* Accept-Language: fr-FR
* User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/18.2 Safari/605.1.15


bestbuy.com doesn't send a spanish speaking version of the site to users with 
Accept-Language: es-US,es-419;q=0.9,es;q=0.8

So we can probably test a Accept-Language override in English without issues. 



In parallel, an outreach effort will be started to contact Best Buy
