Abstract
A system, method, and computer-readable medium having computer-executable instructions for maintaining connections between a mobile device and a server are described herein. In an embodiment, the method operates by receiving a data request from the mobile device, the data request identifying at least a timeout interval. The method comprises sending the data request to a data server and then determining whether the timeout interval has passed. The method also comprises sending a keep alive message to the mobile device indicating that the request has timed out if it is determined that the timeout interval has passed. The method then receives a re post request from the mobile device, the re post request identifying a timeout interval. The method further comprises receiving a response from the data server, the response including at least data requested by the mobile device and then sends the response to the mobile device.
