Abstract: Methods, systems, and articles of manufacture consistent with the present invention provide for servers processing input data regardless of whether the input data is located in an attachment to a message from a client. The server receives a message from the client instructing the server to process data. Then, the server determines whether the data is located in an attachment to the message, and if the data is located in the attachment, moves the data to another location other than in the attachment.

Abstract: In a client and server system the execution of calls is synchronized to maintain a correct execution of a service application. At the server, calls are executed asynchronously by a plurality of threads, and when a thread change occurs, a synchronization call is generated and transmitted to the client, including a server call counter value indicating a number of calls executed at the server. With every synchronization call, the client determines whether the server call counter value corresponds to a current client call counter value. If the counter values are identical, the correct sequence of execution is maintained, but if they differ, an overtake condition has occurred, indicating that service calls from a first thread were overtaken by a second thread. The thread and service calls which have overtaken other service calls are placed into a wait condition to maintain the correct order of execution of service calls.

Abstract: Apparatus and methods are disclosed that download a vanguard-installation-bundle to a computing platform responsive to a set of platform characteristics of the computing platform. The vanguard-installation-bundle includes executable data that includes a platform-dependent set of executable data and a platform-independent set of executable data. The platform-dependent set of executable data is configured to enable execution of the platform-independent set of executable data by the computing platform. The platform-independent set of executable data includes an application program and a sufficient library. The sufficient library is a subset of a reference library. The platform-dependent set of executable data is also configured to invoke installation of the reference library on the computing platform. The method automatically executes the platform-dependent set of executable data on the computing platform and also automatically invokes installation of the reference library on the computing platform.

Abstract: In a data communication system, a client and a server perform a data communication, in particular to provide the client with a instruction data set in response to a content data request message made by client. An instruction format configuration file contains a tree data structure having a plurality of instruction format nodes, each instruction format node indicating a particular combination of instruction elements constituting a particular instruction format and having associated with it a node selection criterion. The program extracts and determines properties from the content data request issued by the client. The program searches the tree data structure with the determined properties in order to find an instruction format node, whose associated node selection condition matches the properties. Thus, the instruction data set returned to the client can be provided in a flexible manner.

Abstract: Methods, systems, and articles of manufacture consistent with the present invention provide for exchanging messages directly between a client and a selected server regardless of the use of a load balancer. The client generates a message to bypass performing load balancing functionality at the load balancer, and sends the message to the load balancer. The load balancing functionality is bypassed and the message is sent directly to the selected server by the load balancer.

Abstract: A method and system are provided for managing files which are modified while the contents of the files are being viewed in a browser window in a data processing system. During execution of the browser, if a request to close a window in the browser is received, it is determined whether a file which was displayed in the window was modified since a last save operation for the file. If the file was modified, and the file had not been saved with the modifications, then an indicator of the modified file is included in a modification list with a reference to enable access to the modified file. The modification list is then sent to a user of the file so that the user may select options for saving the modified file, discarding the modifications, or resuming editing of the file. Thus, integrity of file modifications is enhanced.

Abstract: Methods and systems consistent with the present invention provide an efficient manner of authentication for a plurality of services in a computing environment. When a first service of a plurality of related services is accessed, the user requesting access is provided with a security token that can be used by the user to efficiently access any one of the plurality of services on subsequent accesses. On subsequent accesses after the first access, the user may provide the requested service with the security token which ensures that the user is authorized to use that service. In this manner, the user only needs to provide its authentication information, e.g., log in, once to access any number of related services. This eliminates the need for multiple log-ins for multiple uses of a plurality of services thereby increasing speed, efficiency and reducing time and effort.

Abstract: Methods and systems consistent with the present invention provide efficiency and accuracy for use of plug-ins by installing server-specific plug-ins. Server-specific plug-ins are installed with unique identification, such as MIME types, referencing a specific server so that the plug-in may work in conjunction with that server. In this manner, similar plug-ins installed from different servers can automatically work specifically with its compatible server, thereby increasing flexibility, accuracy and ease of use while reducing ambiguity. As a result, a browser accessing a specific type of data, such as a MIME type, will automatically be directed to the correct server without significant reworking of the system. The decision where to route the activation request may be made in response to the MIME type of the plug-in that was installed.

Abstract: Methods and systems in accordance with the present invention provide flexibility for use of plug-ins by implementing a forwarding plug-in. The forwarding plug-in forwards a user's or application's service request to the appropriate implementation plug-in for processing. In this manner, data files of the same data type, such as a MIME type, can be automatically processed and implemented by different plug-ins, thereby increasing flexibility and ease of use. As a result, different versions of data files of the same data type can be processed automatically without significant reworking of the system. The decision where to route the activation request may be made, for example, by a forwarding plug-in based on a user query via a graphical user input (“GUI”) or configuration data stored with the forwarding plug-in which determines which plug-in is to be used.

Abstract: A method and system for redirecting client requests includes a request handling program at the server. A client request is transmitted from a client via the request handling program to a primary application program. The primary application program generates a redirection instruction based on the client request and returns the redirection instruction to the request handling program. The request handling program, upon receiving the redirection instruction, forwards the client request to a secondary application program selected for serving the request. A response from the secondary application program is returned to the client via the request handling program. A communication session between the client and the primary application program may involve the use of internal resource locators and, for redirecting a client request, internal resource locators may be converted into external resource locators allowing the second application program to access a requested resource.
