Abstract: Content providers may wish to display different versions of content to different users, which may require different versions of the content to be deliverable. The assignment of a particular version of the content to a particular user may also need to persist over time for that particular user. It may be desirable that this functionality occurs at an edge server of a content delivery network, rather than at an origin server. In some embodiments, the edge server may receive a user request including a user identifier for content from a user device; identify an experiment key for the user request based at least in part on the user identifier, the experiment key associated with an experimental version of the content; and transmit an experiment fetch request including the experiment key to an edge cache to retrieve the experimental version of the content.

Abstract: Methods and systems for monitoring a device and a vehicle associated with the device are provided. An example method can comprise monitoring a behavior of a first device in a vehicle, collecting the data associated with the behavior of the first device, and transmitting the data to a second device remote from the vehicle. In an aspect, the first and second device can be a mobile device such as a cell phone, smart phone, PDA, tablet, computer or the like. As an example, the behavior of the device can comprise at least one of a speed, an acceleration, a location, and an orientation, a user authentication, a type of use, and a time of use, whether the device is actively used while device is moving, etc.
