Overview

Receives the Ajax request containing the browser's JavaScript engine's understanding of the user's locale. This is configured in Brut::Framework::MCP, however the requests are initiated from the HTML custom element generated by Components::LocaleDetection. This will set the timezone on the session via Session#timezone_from_browser=, and set the Session#http_accept_language= only if the Accept-Language header did not provide a value that is supported by the app.
