What feature should be changed? Please provide the URL of the feature if possible. ================================================================================== These are zones with URL roots: https://developer.mozilla.org/en-US/Firefox https://developer.mozilla.org/en-US/Add-ons They are at non-standard URLs for wiki docs, but they have standard paths: http://developer.mozilla.org/en-US/docs/Mozilla/Firefox https://developer.mozilla.org/en-US/docs/Mozilla/Add-Ons Most zones are for the purpose of promoting Mozilla-specific technologies, which was a former goal of Mozilla Developer Network. What problems would this solve? =============================== Zone URL roots cause several issues. Here are a few. Each request has to be examined to see if it affected by a zone URL root. This requires database access (to read zone records) or cache access (zone URL roots are cached). This causes performance and caching problems. Zone URL roots have to be special-cased in code and 3rd-party tools, such as Google Analytics and CloudFront, to categorize them as wiki document pages. This causes problems with metrics and dashboards, and often results in bugs that are not discovered until changes go to production. Some tools, like KumaScript, expect the "standard" path for a zoned document, while other code only works with the external URL. For most documents, the standard path is identical to the external path, so most changes are tested on these. The difference between the zoned and non-zoned URLs is a source of many bugs. Zone URL roots are poorly implemented across locales. Each locale requires its own zone record, linking the zone URL root with the translation in that locale. The zone record can't be created until the first translation is created. Many locales don't include the relevant zone, and many zone URL records are incorrect for seldom-used locales. This is a source of confusion for visitors. Who would use this? =================== Developers and MDN visitors What would users see? ===================== Developers would add redirects from current zoned URLs to the standard URLs and remove the request parsing that handles zoned URLs. Visitors would get a redirect from the zoned URL to the standard URL, What would users do? What would happen as a result? =================================================== Developers would see less bugs and faster time to feature completion. Lots of code that supports or works around zones can be removed and refactored. Django and functional tests can be updated and simplified. Visitors would see the same content as before, at different URLs/ Is there anything else we should know? ====================================== There is a related feature for custom styles for zones. This will be retained. Zone URLs are currently implemented with permanent redirects (301) from the standard URLs to the zoned URLs. These should be changed to temporary redirects for at least a few weeks before the redirects are changed from the zoned URLs to the standard URLs
