Abstract: A computing system, method and product comprising a server, a mobile device comprising a client interconnected with the server via a data network, the client identified by a credential which is unavailable to the client and an intermediate node interconnected to the client and the server via the data network wherein the credential is available to the intermediate node. Upon reception of a service request from the client at a first server address the server redirects the client to transmit the service request to a second server address via the intermediate node together with a token, wherein the intermediate node appends a credential identifying the client to the redirected service request and the token and relays the redirected service request, the token and the credential to the second server address.

Abstract: There is described an interconnect hub for routing an Instant Message (IM) or related communication between a sending IM device in a first IM community and a recipient IM device in one of a plurality of potential second IM communities. The interconnect hub comprises a router for determining the destination of IM communications and routing the IM communications to the intended recipient, a search function for finding the service provider providing IM services to the user identifier, and a cache comprising a plurality of records associating user identifiers with corresponding service providers (mobile or Internet). When the IM communication is received by the interconnect hub, the router examines the recipient user identifier, accesses the cache keying on the recipient user identifier, retrieves the service provider associated with the recipient user identifier, and forwards the IM communication to the associated service provider for delivery to the intended recipient.
