20090083407CRISSCROSS CANCELLATION PROTOCOL - Technologies, systems, and methods for ordered message delivery that avoid message races or crisscrosses between communicating nodes. For example, if Node A sends message 3 towards Node B and, shortly thereafter, Node B sends message X to Node A, Node A would like to know whether or not message X reflects Node B's state after receiving message 3. If Node B received message 3 prior to sending message X, then proper state may be maintained between the nodes. But if messages 3 and X crisscrossed, or if message 3 was never properly received by Node B, then the state between the nodes may be corrupt. Technologies, systems, and methods are provided to avoid such corruption.03-26-2009

An instantiation of a user interface may be created on the hosting webpage that has an ability to control display properties of the cross-domain frame, thereby controlling display properties of the ad content in the cross-domain frame. Further, a task manager may be utilized as part of the user interface to facilitate a host of the hosting webpage to manage ad content.12-03-2009
20090327869ONLINE AD SERVING - Online ad hosting (e.g., hosting ads from one domain on a webpage from a different domain) is accomplished using an insulator cross-domain frame (e.g., an inline frame (IFrame)), into which a third party may load content, source code to detect events associated with the third party content (e.g., detecting if ad content wishes to expand), and a communicator same-domain IFrame for sending requests to the host webpage associated with detected events. That is, a cross-domain IFrame may be created in a host webpage, which can isolate an ad from the host webpage. A communicator frame may be utilized to communicate text messages between the contents of the cross-domain frame and the host webpage. Further, an API can be used to apply parameters, restrictions and allowable events to the third party content in the insulator IFrame.12-31-2009
