Abstract: A method, apparatus and computer program product for reducing the data transmitted over an external communication link from a first application resident in a first computer to a second application resident in a second computer. The method, apparatus and computer program product include storing a data stream from the first application to be provided to the second application in response to a request from the second application in a cache resident in the first computer to create a server base cache entry and in a cache resident in the second computer to create a client base cache entry. Requests from the second application are interrogated to determine if a client base cache entry corresponding to the interrogated request exists and to determine if a server base cache entry corresponding to the interrogated request exists. The response data stream is intercepted prior to transmission of the response on the external communication link and compared to the server base cache entry to provide difference data corresponding to the difference between the intercepted response and the server base cache entry. The difference data is sent over the external communication link and acquired by the second computer which reconstructs the response data stream by combining the client base cache entry with the difference data to create a response data stream which is provided to the second application.

Abstract: Methods, systems and computer program products are provided for communicating with a web browser executing on a remote/mobile processing system which is temporarily and intermittently connected to a second computer. According to the present invention, requests from the web browser to a server application accessible to the second computer are stored in a persistent request queue at the remote/mobile processing system. An interim response is provided to the web browser in response to the request from the client application. The stored request may be recalled to allow user modification of the stored request prior to the request being provided to the second computer for transmission to the server application.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: Methods and systems provide for communicating with a web browser executing on a remote/mobile processing system which is temporarily and intermittently connected to a second computer by storing, in a persistent request queue (230-232) associated with a user identifier at the second computer, a request from the web browser (10) to a server application accessible to the second computer. By storing the requests at the server side the requests may be processed after disconnection from the remote/mobile processing system. A list of stored requests may be provided to the web browser for presentation to a user, along with the availability of received responses. HTML forms are used, e.g. for patient admission.

Abstract: Methods and systems are provided for communicating with a web browser (10) executing on a remote/mobile processing system (5) which is temporarily and intermittently connected to a second computer. Requests e.g. on HTML forms from the web browser (10) to a server application accessible to the second computer are stored in a persistent request queue (32) at the remote/mobile processing system (5). An interim response is provided to the web browser (10) in response to the request from the client application. The stored request may be recalled to allow user modification of the stored request prior to the request being provided to the second computer (6) for transmission to the server application. Thus a patient admission form could be edited to correct errors or be resubmitted with new data for a different patient. By storing requests in a request queue and providing an interim response to the web browser asynchronous operation of the web browser is achieved.

The method, apparatus and computer program product include storing a data stream from the first application to be provided to the second application in response to a request from the second application in a cache resident in the first computer to create a server base cache entry and in a cache resident in the second computer to create a client base cache entry. Requests from the second application are interrogated to determine if a client base cache entry corresponding to the interrogated request exists and to determine if a server base cache entry corresponding to the interrogated request exists. The response data stream is intercepted prior to transmission of the response on the external communication link and compared to the server base cache entry to provide difference data corresponding to the difference between the intercepted response and the server base cache entry. The difference data is sent over the external communication link and acquired by the second computer which reconstructs the response data stream by combining the client base cache entry with the difference data to create a response data stream which is provided to the second application.
