Thus, each client system, when outputting the communication, displays the selection of mirrored site address accessible to the intended recipient accessing that client system.

Abstract: Enabling the user to link a selected sequence of hypertext World Wide Web (Web) documents into a string and to store the string at his receiving Web display station so that these documents will be available for his use. An implementation at a receiving display station is provided for designating a received Web document as a starter document and for selecting a subsequently received Web document as a first next document. An implementation is provided for creating a hyperlink in the starter document to the first next document, together with means for storing said starter and next documents at said receiving display station. The invention further provides for an extension of the selected documents into a string through selecting one or more subsequently received Web documents as a subsequent next document and creating a hyperlink in the first next document to the subsequent next document.

Abstract: Administration of keyboard input in a computer having a display device supporting a graphical user interface (“GUI”), including storing keyboard input intended by a user for a second widget when keyboard focus is on a first widget, wherein the first widget receives no keyboard input; changing keyboard focus to the second widget; and providing the stored keyboard input to the second widget.

Abstract: A method of data processing in a data processing system includes an operating system shell receiving a command identifying a target executable. In response to receiving the command, the operating system shell determines whether or not a directory re-order option is set. In response to determining that the directory re-order option is set, the operating system shell locates the target executable by searching one or more file system directories for the target binary executable in accordance with an order indicated by a set of dynamic weights associated with directories among said one or more file system directories. The set of dynamic weights is then updated based upon the determined location of the target executable in the file system.

Abstract: A computer implemented method, data processing system, and computer usable program code are provided for migrating a persistent cache. A priming request is received at an intermediary to prime the persistent cache of a first partition. Data is moved from a disk to the persistent cache and, responsive to the data being moved to the persistent cache, an unmounting command is issued to unmount a first file system in the first partition from the persistent cache. A mounting command is then issued to mount a second file system in a second partition to the persistent cache, wherein the second partition may now use the data contained in the persistent cache.

Abstract: A computer implemented method, apparatus and computer usable program code for processing e-mail messages. In response to a selection of a particular e-mail message from a sender as being undesired, a message identifier is stored in the e-mail message, wherein the message identifier uniquely identifies the e-mail message and any subsequent replies based on the e-mail message. Further, in response to receiving another e-mail message, the another e-mail message is processed using a policy to filter out e-mail messages containing the message identifier, wherein subsequent e-mail messages from the sender without the message identifier are unfiltered.

The calculated digital digest is compared with a set of digital digests from a trusted source. The application is executed if a match between the calculated digital digest and set of digital digests occurs.

Abstract: A method, system, and program for automated distribution of an instant messaging request for an unavailable intended recipient to a backup recipient are provided. A chat support system detects a particular messaging request from a requester for initiating a communication with an intended recipient who is unavailable to respond to the messaging request and, in response, the chat support system selects a backup recipient designated to receive the particular messaging request. The chat support system then directs the opening of a communication channel for a messaging session between the requester and the backup recipient. Then, the chat support system detects a message log of at least one message entry for the messaging session between the requester and the backup recipient.

Abstract: A method, system, and program for automated selection of a backup recipient and distribution of an instant messaging request to the backup recipient are provided. A communication support system detects a messaging request initiated by a requester for an intended recipient. The communication support system determines whether the intended recipient is available to respond to the messaging request from the requester. If the intended recipient is unavailable to respond to the messaging request from the requester, the communication support system searches at least one of a directory entry, a backup directory entry, and a schedule entry for the intended recipient to identify a designated backup for the messaging request.
