Abstract: Described are techniques for facilitating communications between a client and a server. A first communication connection is opened between the client and server and remains open for a duration of a session. In response to receiving a client request, a second communication connection is opened. The client request is sent over the second communication connection to the server. A first response is sent to said client over the second communication connection. The second communication connection is closed. The client request is serviced and a data portion indicating a status is sent to the client over the first communication connection. The data portion is included in a second response sent from the server to the client over the first communication connection. If there are other client requests received by the server and processed during the session, additional data portions for the other client requests are included in the second response.

Abstract: Described are techniques for providing a publication notification in a data storage system. An active element manager component is used to perform data storage management operations for the data storage system. A feed aggregator in the data storage system aggregates feed items from one or more feeds. Each of the one or more feed items are associated with one of said feeds and indicates a publication notification for data associated with said one feed.
