You can design a filter that intercepts a client request to connect to the Internet, and instead provide the information from another source. In this case, you are emulating an outside connection, and the client is unaware that the data is coming from a source other than the requested external one. An HTTP filter that provides a Web object from a cache is emulating a connection.
An inbound connection can also be emulated. For example, a filter can emulate a connection on a single well-known port, so that a number of client machines can effectively use the connection simultaneously.
