Abstract
Data are pushed from a source to a destination via an intermediate computer system. If the intermediate computer system is unable to forward the pushed data to the destination for a predetermined length of time, the intermediate system deletes the pushed data and never forwards the data to the destination. According to another aspect, the intermediate system receives a command, e.g. from a server originating the data, to delete the data if the data has not yet been forwarded to the destination. According to another aspect, the intermediate system receives data whose identifier (e.g. source URL) matches an identifier of data pushed earlier to the same destination but not yet forwarded. The intermediate system deletes the earlier pushed data and never forwards the earlier pushed data.
