A sender email client, in response to a request to send an email with attachment, determines whether a recipient of the email has distributed storage separate from an incoming email server of the recipient for storing email attachments. If so, a location server is consulted for the distributed storage's network address and its availability is determined. The send request is then serviced accordingly. An email service, in response to receiving an email with attachment, determines whether a recipient of the email has distributed storage for storing email attachments. If so, its network address and availability are likewise determined. The attachments are forwarded to the recipient's distributed storage for storage, when it becomes available. An email recipient client, in response to a request to access an email attachment, retrieves the attachment from the recipient's distributed storage or the incoming email server, as appropriate.

A system and method for collaborative filtering of data, such that accurate real time recommendations can be provided to users, without prior rating by users. The invention's main purpose is to discover the purchasing patterns of the users (customers) of a particular vendor (this includes stores or other points of sale, such as service businesses), whether they are virtual places on the Internet or conventional offline places. The present invention operates in two stages: In the preliminary stage the system reads the previous sales transactions, and makes various queries on previously collected user data, deriving rules. In the second phase, a user making a new request sends the request to the software component, where it is processed in relation to the rules. The result of this processing is a derivation of predictions and alerts concerning the users' information or purchase requests. The system also checks user baskets in order to predict if there are preferred items that have not been included, or determine whether there are unexpected items that may indicate buying mistakes or security warnings. The best modes of the invention are for use in online virtual stores and offline conventional stores. Such stores may be shops, vendors or service providers.

A method and system provide a user device with secure access to an enterprise application in an enterprise network through VPN. The enterprise application is accessed from a user device such that it sends and receives data packets through the VPN client. For this, a request to send packets, originating from the user application, is intercepted by a VPN agent associated with the user application. In turn, the VPN agent associates an address of a loop-back interface with the user application. Thereafter, packets sent by the user application, are re-directed to the VPN client through the loop-back interface. Similarly, packets received by the VPN client from the enterprise network are routed through the loop-back interface to the user application.
