Abstract
A method comprises a server receiving a message from a device requesting content, reading a first time record for the previous receipt of content, comparing the first time record with a second time record for the content stored in cache, and sending, when the second time record is newer than the first time record, the requested content. When time records match, the device is advised of refresh time and to request later. When the message lacks a time record, the requested content is sent. When cache does not contain requested content, a data loader obtains content from a server. A message to the device advises the time to obtain the content and to request again later. When cache does not contain the content and the server is unavailable, the data loader determines the time of network availability. A message then advises of availability time and to request again later.
