About this extension
This extension enables developers to debug the MediaWiki platform that Wikimedia Foundation projects run on. It does so by injecting the X-Wikimedia-Debug HTTP header, only when browsing Wikimedia Foundation websites.

Requests bearing this header are not cached and are routed to the selected debug server.
