Abstract: Disclosed is a system, method, and program for caching files retrieved from a server over a network. A computer system receives a request from a requesting computer system for a file maintained on the server. The computer system is capable of communicating with the server via the network. The computer system retrieves the requested file from the server over the network and stores a copy of the requested file in a primary storage. The computer system further returns another copy of the requested file to the requesting computer system. The computer system determines retrieved files to migrate from the primary storage to a secondary storage and migrates the determined retrieved files from the primary storage to the secondary storage. To determine the files to migrate from primary storage to secondary storage, the computer system may determine a distribution of file requests per unit of time according to file size for files maintained in the primary storage and the secondary storage.

Abstract: A method and apparatus for the re-routing of e-mail sent to a prior address (or an address that is non-working, or temporarily inconvenient) to the new address of an intended recipient. E-mail that is to be sent to a recipient is sent to the former Internet Service Provider (ISP). Because the recipient is no longer a subscriber to the old ISP, or because the address at the old ISP is temporarily inconvenient, the e-mail is re-routed to a re-route server of the present invention. The re-route server then causes the e-mail to be sent to the correct address through a variety of processes. Alternatively, new e-mail addresses are made available at the old ISP. The old ISP can then forward e-mail messages directly to the new ISP.

Abstract: A system and method for pushing information from a host system to a mobile data communication device upon sensing a triggering event is disclosed. A redirector program operating at the host system enables a user to continuously redirect certain user-selected data items from the host system to the user's mobile data communication device upon detecting that one or more user-defined triggering events has occurred. The redirector program operates in connection with event generating applications and repackaging systems at the host system to configure and detect a particular user-defined event, and then to repackage the user-selected data items in an electronic wrapper prior to pushing the data items to the mobile device. The system includes attachment processing components for identifying one or more attachment displayers in the vicinity of the mobile data communication device and then routing an attachment from the host system directly to a selected attachment displayer.

Abstract: A method and apparatus checks a set of files against a manifest to determine whether to accept or reject the files. The manifest contains one or more policy sections that describe whether to accept files that are described in the manifest but not received, or received but not described in the manifest. The method and apparatus determines whether files are listed in the manifest but not received, or received but not listed in the manifest, and can accept the files in these circumstances based on the policy section of the manifest. The manifest may also contain a hash result for each file. The method and apparatus can hash the files received and compare the hash result produced with the hash result specified in the manifest. If the hash results computed for the file are different from the hash result for the file in the manifest, the file or the set of files may be rejected.

Abstract: A system and method for downloading compressed images from an Internet server to a consumer's computer is described. Two Windows® threads manage the process of downloading, decompressing and rendering images to the consumer's display. A first binding thread manages communication between the server computer and the consumer's computer, while a second worker thread oversees decompressing and rendering all of the images. The downloaded images are sent by the binding thread to a temporary buffer, wherein the worker thread instructs a decoder object to begin processing all of the data within the specified buffer. As the decoder object decompresses the data in the buffer, the decompressed image data is sent to a bitmap file. A rendering object reads the bitmap file and paints the downloading image to the consumer's display.

The bypass elements each have an address store which can be selected only in the event of the address interrogation and which is inactive during data interchange.

Abstract: A method of building and assembling programs across computer networks that is dictated by the user to perform logical work without the user using a compiler. Users are able to assemble programs over a network by defining or re-defining which logical components are bound into the overall program without the use of a compiler. Logical components are called and bound into the program at run time, allowing dynamic programming which may be modified at any time without re-compiling the entire program. Each logical component can act independently of other logical components or work in concert with each other. This allows assembly of a program, even though some components may be created using totally different methodologies and/or are constructed by different programmers.

Abstract: A method and system is disclosed for detaching Java applets from the constraints of the application such as a browser which provides the Java engine for executing those applets. Thus, the applets, when detached, can appear in a detached window which is more easily controllable by the operating environment desktop. The Java applets continue to run under the application's virtual machine but do so without regard to the graphical interface limits of the application. Further, if the application that launched the applet proceeds to a new URL location, the Java applet continues to run. Also, the applet, once detached, can be reattached into the application to appear in the application history.
