Abstract
Features are provided for the use of persistent connections and efficient content synchronization in content delivery environments. A content management system may provide content feeds to user devices using a persistent duplex connection over which the content management system and user devices may communicate asynchronously. By using a persistent duplex connection to asynchronously communicate with user devices, the content management system can provide content for the content feeds while, in parallel, receiving requests and commands from the user devices, responding to the requests and commands, and transmitting other requests and commands to the user devices. In addition, the content management system and a particular user device can exchange information regarding the content items that the user device has or should have already received.
