In the .htaccess file for www.mozilla.org (in the main base, which is the old .com tree), there is the following RewriteCond/RewriteRule block. # Handle file paths off the root, and add the locale back into the path # based on the server name and/or domain. # Examples: # http://{locale}.www.mozilla.com/firefox/central/ -> # http://{locale}.www.mozilla.com/{locale}/firefox/central/ RewriteCond %{SERVER_NAME} !^www\..* RewriteCond %{SERVER_NAME} ^(\w{2,3})(-\w{2}(-mac)?)?\..* RewriteCond %{REQUEST_URI} !^/(\w{2,3}(-\w{2}(-mac)?)?)(/.*)?$ RewriteCond %{SCRIPT_FILENAME} !^.*(php|css|js|jpg|gif|png|ico|pdf|swf) RewriteRule ^(.*)$ /%1${toupper:%2}/$1 [R=permanent,L] This is ostensibly designed to properly redirect subdomains containing the locale to their proper path. The problem is that it matches some requests which it shouldn't. Specifically, it assumes any 3-character subdomain that isn't "www." must be a locale. This assumption broke recently when a CDN was using the subdomain as a *location* tag (sjc.mozilla.com, phx.mozilla.com, etc). As I understand it this was never actually used in production. It certainly isn't in use now, so at most this is legacy functionality. In fact, I believe this may not actually even be reachable as intended: A request for "en-us.www.mozilla.com" results in an immediate 301 redirect to http://www.mozilla.org/firefox/, which is *not* what this block is trying to do. So, this block doesn't actually trigger when it's intended to. Would you be willing/able to remove this altogether?

If I remember well, this was to deal with hardcoded urls in older versions of Firefox (2.0 I think) which had urls hardcoded in the product in the form ab-CD.www.mozilla.com/ab-CD/path/to/page I would be glad to have this hack removed though :)

James, Steven, Rik - Thoughts here? Can one of you take a look?

(In reply to Laura Forrest from comment #2) > James, Steven, Rik - Thoughts here? Can one of you take a look? I don't know of any uses of the ab-cd.* URLs that are still in use.

Yeah, I'm all for this. Scheduled for next week.

There is also some code in include/prefetch.php, line 53: if ($lang == null) { // We're hoping they went to a specific host like en-us.mozilla.org. list() will // give us the first chunk. list($lang) = explode('.',$_SERVER['SERVER_NAME']); // If it's in our language array, we've got content, we're good to go. if (!in_array($lang, array_map('strtolower', $full_languages))) { $lang = null; } }

Unassigning bugs from James that are not migration-related bedrock platform bugs. Let me know if you have any questions.

Rik, James, was this ever implemented? If not, is it still valid or can we resolve?

.htaccess is gone from www.mozilla.org.
