An apparatus, method and computer program product for efficiently pooling network client-server connections. The apparatus is implemented within an interface unit connecting a plurality of servers to the Internet, which is in turn connected to a plurality of clients. The method includes the steps of opening a connection between a first client and the interface unit; determining whether a connection between the interface unit and a server is finished being utilized by the first client; opening a connection between a second client and the interface unit; if no free connection is open between the interface unit and the server, then allowing the second client to access information on the server via the same connection utilized by the first client without waiting for the first client to initiate closing the connection; and delinking the connections between the first and second clients and the interface unit while keeping open the connection between the interface unit and the server.

A method for maximizing server throughput while avoiding overload of a server is presented. The method involves intercepting, via an interface unit, a client request for information from the server. Next, the interface unit determines the current server performance, where the server performance is based on the number of connections opened to the server, the response time of the server and the rate at which the response time is changing. Finally, the interface unit forwards the client request to the server if the current server performance is close to an optimal performance, whereby avoiding overload of the server.

A system, method and computer program product for communicating with a private network are described. An application of a client is monitored for communications intended for a node coupled to a private network. A communication from the monitored application of the client that is intended for the node may then be intercepted before the communication can be received by the transport layer of the client, the intercepted communication may then be sent with a connection identifier to an interface unit coupled to the private network via an established network connection over a public network. The connection identifier also associated with a communication link that is established over the private network between the interface unit and the node. The interface unit uses the connection identifier that is received with the communication to identify the associated communication link over the private network. The interface unit may then send the communication (without the connection identifier) to the node via the identified associated communication link.

An apparatus, method and computer program product for guaranteeing network client-server response time while providing a way of putting the client on-hold when the response time temporarily prohibits access to the requested server. The apparatus is implemented within an interface unit connecting a plurality of servers and an on-hold server to the Internet, which is connected to a plurality of clients. According to one aspect of the invention, the method includes the steps of opening a connection between a client and the interface unit; determining which server the client desires a page from; determining the current response time of the requested server; if the response time is acceptable then opening a connection between the interface unit and the requested server if no free connection is open between the interface unit and the requested server; allowing the client to access information on the requested server via the connections; and closing the connection between the client and the interface unit while keeping open the connection between the interface unit and the requested server. Alternatively, if the response time is not acceptable, then putting the client on-hold by redirecting the client to an on-hold server until the response time of the requested server becomes acceptable. According to a 'on-hold distribution' aspect of the invention, the interface unit determines the on-hold preference of the client and selects the server hosting that on-hold preference. According to another aspect of the invention, instead of utilizing the interface unit, each server has the intelligence to put the client on-hold when applicable.

An apparatus, method and computer program product for network client-server multiplexing. The apparatus is implemented within an interface unit connecting a plurality of servers to the Internet, which is connected to a plurality of clients. According to a 'connection pooling' aspect of the invention, the interface unit opens and maintains connections with the servers and handles the opening and closing of connections with clients accessing the servers, thereby freeing the servers of the processing load incurred by opening and closing connections. According to a 'connection distribution' aspect of the invention, the interface unit examines the path names within requests received from clients and selects the server hosting the requested information according to the path names.

Alternatively, if the response time is not acceptable, then putting the client on-hold by redirecting the client to an on-hold server until the response time of the requested server becomes acceptable. According to a &ldquo;on-hold distribution&rdquo; aspect of the invention, the interface unit determines the on-hold preference of the client and selects the server hosting that on-hold preference. According to another aspect of the invention, instead of utilizing the interface unit, each server has the intelligence to put the client on-hold when applicable.
