497316 - Incorrect language negotiation happening with English

Status: RESOLVED DUPLICATE of bug 439568

(addons.mozilla.org Graveyard :: Public Pages, defect)

Description

[Matthew Somerville]

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-GB; rv:1.9.0.10) Gecko/2009042315 Firefox/3.0.10
Build Identifier: 

The HTTP specification states: "A language-range [in an Accept-Language
request header] matches a language-tag [in a variant] if it exactly
equals the tag, or if it exactly equals a prefix of the tag such that
the first tag character following the prefix is "-"." - ie. the request
can be a prefix of the document language.

If you set your browser to ask for English then French (ie. an Accept-Language header of e.g. "en, fr;q=0.5") then http://addons.mozilla.org will redirect you to the French front page when it should redirect to the English front page. I assume this is because the server has locales of en-us and fr, and so is not matching up on the prefix.

Reproducible: Always

Steps to Reproduce:
1. Set Firefox languages to be en, fr, in that order.
2. Go to http://addons.mozilla.org/

Actual Results:  
You are redirected to the French front page.

Expected Results:  
You should be redirected to the English front page.
