Abstract
A communication protocol for distributing information related to a resource in substantially real-time to a subscriber includes a first HTTP request message for allowing the subscriber to request a subscription to the information related to the resource, where the first HTTP request message includes subscription data in a header and/or in a Uniform Resource Identifier (URI) reference associated with the first HTTP request message, and the subscription data identifies the first HTTP request message as a subscription request. The communication protocol also includes a second HTTP request message for allowing a publisher to update the information related to the resource, and an HTTP response message for allowing a publish/subscribe service to notify the subscriber of the updated information related to the resource each time the publish/subscribe service receives the second HTTP request message from the publisher.
