When a server receives a request for an information payload from a remote device, the server may determine the device's type and identify an optionally-installable application that can be used to access the information payload on devices of that type. When the optionally-installable application is not installed on the remote device, the server may store a identifier for the remote device and send the device a redirection message via which the device can obtain and install the application. Subsequently, when the server receives an installation indication from the application executing on a remote device, the server may identify the device as having recently been redirected to install the application and store or update a record indicating that an application-installation event occurred.
