A method of updating or rebasing templates for information sent across a relatively slow transmission link such that only changed information is transmitted across the links. In addition, the information is updated such that the information transmitted across the links is minimized by updating the templates based on the characteristics of the data being sent. 7

Method and apparatus for optimal rebasing of web page transmission using a plurality of different rebasing tests and a Cost-Effectiveness determination

A method and system for efficiently updating container objects on remote systems. The method and system involve a server extension which determines whether the files within the container object have changed since the last time they were sent to the client. If they have changed, the server extension sends only the changed files with instructions on how to reconstruct the container object to a client extension. The client extension receives the changes and the instructions and reconstitutes the container object and transmits the container object to the client browser.

Method and system for differencing container files

A method of updating or rebasing templates for information sent across a relatively slow transmission link such that only changed information is transmitted across the links. In addition, the information is updated such that the information transmitted across the links is minimized by updating the templates based on the characteristics of the data being sent.

Method and apparatus for optimal rebasing of web page transmission

Systems, methods, and computer program products provide a graphical user interface for a data processing system wherein a foster window associated with a secondary application program can be removably attached to a primary application window associated with a primary application program, such as a Web browser. The foster window can be automatically repositioned and/or resized in response to repositioning and/or resizing of the primary application window, such that the first and second windows maintain a generally rectangular attached configuration.

A method, apparatus and computer program product for caching data received from a first application and to be provided to a second application in response to a request from the second application. The method apparatus and computer program products including storing a data stream to be received from the first application and to be provided to the second application in a cache to create a client cache entry corresponding to the request from the second application. The time of creation of a client cache entry is also stored to create a client cache entry time record. Requests from the second application are interrogated to determine if a client cache entry exists corresponding to the request. The client cache entry time record for the client cache entry corresponding to the request from the second application is evaluated to determine if the client cache entry corresponding to the request from the second application was created within a predetermined client coherency time interval prior to the second application requesting the information. The client cache entry is supplied to the second application in response to the request if a client cache entry for the request from the second application was created within a predetermined client coherency time interval prior to the second application requesting the information.

Methods, systems and computer program products for the synchronization

A method, apparatus and computer program product for reducing the data transmitted over an external communication link using the TCP protocol from a first application resident in a first computer and to a second application resident in a second computer. The method, apparatus and computer program product include establishing a first virtual socket in the first computer in response to each connection request by the first application for receiving request data originated by the first application. A first real socket in the first computer and a second real socket in the second computer are established to connect the first computer to the second computer over the external communication link and are maintained until the request data has been provided to the second application. In the second computer a second virtual socket is established for each connection request by the first application wherein the second virtual socket corresponds to a first virtual socket established in the first computer in response to a connection request by the first application. Request data associated with a first virtual socket is multiplexed onto the first real socket and transmitted over the external communication link utilizing the TCP protocol. The multiplexed request data is received from the external communication link by the second real socket and demultiplexed. The demultiplexed request data is provided to the corresponding second virtual socket which provides the request data to the second application.

Method and apparatus of using virtual sockets for reducing data

A method, apparatus and program product for increasing the performance of a client/server system having a client application resident on a first computer and communicating with a server application resident on a second computer remote from the first computer. The client application and the server application utilize a client/server independent communication protocol for communication between the client and the server and at least one segment of the communication between the client application in the first computer and the server application in the second computer occurs over an external communication link. The method, apparatus and program product intercept communications in the client/server independent communication protocol originated by the remote client prior to transmission of the communications on the external communication link and convert the communication originated by the client to a second client/server specific communication protocol. The converted communication is transmitted over the external communication link and received from the communication transmitted over the external communication link. The communication received over the external communication link is converted from the client server specific communication protocol to the client/server independent communication protocol and the communication originated by the remote client is provided to the server in the client/server independent communication protocol. Differencing, caching or protocol reduction techniques increase performance over the external communication link. The applications may be a web browser and a web server and may communicate over a wireless communication link.
