Overview

Filters are tests that get run against a request to determine if it’s a mobile request or not. A filter can return true, false or nil. The first non-nil value of the filter chain is the one that gets used and this also gets used to mark the session as a “mobile session”

You can manipulate the chain to add new conditions that check on e.g. request format.
