Entity that, in the interest of efficiency, essentially stands in for another entity.

Editorial note  Needs to be clarified; see gateway node that relays a message between a client and a Web service, appearing to the Web service to be the the client.

A gateway that relates one session on the net to another.

A person who represents another, or a document granting representation to another.

A security or index whose correlation with another security or index is so strong that it is used as a substitute for the other.

A gateway that relays one Internet session to another.

This is the gateway to a network. All communications to and from the network must pass through the proxy. This protects a network by creating only one point of entry that needs to be thoroughly secured. It has a side benefit of making any communications from the inside of the network appear to be coming from the proxy -- thus making it more difficult for crackers on the outside to know which particular internal computer a specific piece of information is coming from.

An interface-specific object that provides the parameter marshaling and communication required for a client to call an application object that is running in a different execution environment, such as on a different thread or in another process. The proxy is located with the client and communicates with a corresponding stub that is located with the application object that is being called.
