A method to confirm delivery of data to a receiving device via a sending socket is disclosed. One embodiment of the method comprises determining when a predetermined amount of data has been removed from a send buffer of the sending socket and sending a confirmation when the predetermined amount of data has been removed from the send buffer. Other embodiments are described and claimed.

Confirmation of delivery of content to an HTTP/TCP device

An intermediary node on a data communications network implements a flow control algorithm to control network congestion. The intermediary node receives messages destined for servers or other upstream nodes from clients or other downstream nodes and determines whether to forward the messages based on the flow control algorithm, which may be adaptive. The algorithm may consider explicit back-off messages received from upstream nodes, failure of upstream nodes to respond to messages forwarded by the intermediary node, and/or other criteria. When a back-off condition applies, the intermediary node refrains from forwarding messages it receives and sends back-off messages to nodes initiating the messages. Back-off messages may include a back-of time period and/or other back-off criteria.

Method and apparatus for controlling network traffic

The invention provides a method of using a communications device to access an on-line service provided by a network server. In one embodiment of the invention, a mobile telephone is used to establish a connection with a proxy server. The mobile telephone is then used to establish a second connection with a network server on which hypermedia information is stored. The second connection is a secure end-to-end connection which may be achieved by either tunneling through the proxy server or by bypassing it entirely. The second connection is used to send a secure request for hypermedia information to the network server. If it is determined that, in order to service the request, additional information is required, then the mobile telephone is notified and a service capable of providing the additional information is accessed remotely in the proxy server by sending a communication to the proxy server via the first connection.
