| 20090307282 | MERGING FILE DIRECTORIES - A merge method includes determining whether a source item in a source file directory is a file or a subdirectory. If the source item is a file, any conflicting items in a destination file directory are deleted and the file is moved from the source file directory to the destination file directory without copying the file. If the source item is a subdirectory that has no corresponding destination subdirectory in the destination file directory, the subdirectory is moved from the source file directory to the destination file directory without copying the subdirectory. If the source item is a subdirectory that does have a corresponding destination subdirectory, the merge method is repeated for each item of the source subdirectory. | 12-10-2009 |

| 20090055646 | DISTRIBUTED MANAGEMENT OF CRYPTO MODULE WHITE LISTS - An apparatus and method for managing the distribution and expansion of public keys held by a group or array of systems in white lists. The addition of a new system to the array entails a manual input to authorize the introduction of the new system to one trusted system in the array. After the introduction the new system is trusted by the one member and the white list of the one member is loaded into the white list of the new system. The new system then requests joining each of the other systems in the array. For each system in the array asked by the new system, the systems in the array ask if any other systems in the array already trust the new member. In response, a system of the array that trusts the new system responds by sending its white list (containing the public key of the new system) to the requesting system. Eventually the public key of the new system is in the white lists of all the systems in the array. In practice this trusts expansion occurs in the background with respect to running applications. | 02-26-2009 |

| 20090031311 | PROCESSING TECHNIQUES FOR SERVERS HANDLING CLIENT/SERVER TRAFFIC AND COMMUNICATIONS - The present invention relates to a system for handling client/server traffic and communications pertaining to the delivery of hypertext information to a client. The system includes a central server which processes a request for a web page from a client. The central server is in communication with a number of processing/storage entities, such as an annotation means, a cache, and a number of servers which provide identification information. The system operates by receiving a request for a web page from a client. The cache is then examined to determine whether information for the requested web page is available. If such information is available, it is forwarded promptly to the client for display. Otherwise, the central server retrieves the relevant information for the requested web page from the pertinent server. The relevant information is then processed by the annotation means to generate additional relevant computer information that can be incorporated to create an annotated version of the requested web page which includes additional displayable hypertext information. The central server then relays the additional relevant computer information to the client so as to allow the annotated version of the requested web page to be displayed. In addition, the central server can update the cache with information from the annotated version. The central server can also interact with different servers to collect and maintain statistical usage information. In handling its communications with various processing/storage entities, the operating system running behind the central server utilizes a pool of persistent threads and an independent task queue to improve the efficiency of the central server. A task needs to have a thread assigned to it before the task can be executed. The pool of threads are continually maintained and monitored by the operating system. Whenever a thread is available, the operating system identifies the next executable task in the task queue and assigns the available thread to such task so as to allow it to be executed. Upon conclusion of the task execution, the assigned thread is released back into the thread pool. An additional I/O queue for specifically handling input/output tasks can also be used to further improve the efficiency of the central server. | 01-29-2009 |
