A method and apparatus for booting a client data processing system from a set of boot images stored on a server data processing system. At power up of the client data processing system, an image request is sent to the server data processing system from the client data processing system. According to a state of the client data processing system, an initial boot image is selected and sent to the client data processing system. The state of the client data processing system is monitored. Responsive to an indication that the client data processing system needs to be rebooted, a new boot image is selected, if needed depending on the state, and sent to the client data processing system. This selection is made according to the state of the client data processing system at the time the indication is identified. The client data processing system is rebooted using the boot image from the server data processing system.

Method and apparatus for managing boot images in a distributed data processing system

A method of copying a Web page presented for display on a browser of a Web client. The Web page comprises a base HTML document and a plurality of hypertext references, one or more of which may be associated with embedded objects (such as image files). The operation begins by copying the base HTML document to the client local storage and establishing a pointer to the copied document. A first linked list of the hypertext references in the base document is then generated. Thereafter, and for each hypertext reference in the first linked list, the following operations are performed. If the hypertext reference refers to an embedded object in the base HTML document, the embedded object is saved on the client local storage and the file name of the saved embedded object is stored (as a fully-qualified URL) in a second linked list. If the hypertext reference does not refer to an embedded object in the base HTML document, the fully-qualified URL of the hypertext reference is stored in the second linked list. Then, the fully-qualified URLs of the second linked list (including those associated with the stored images) are updated to point to the files located on the client local storage. At the end of this operation, there is a new HTML page with links for images pointing to files on the local hard drive. When the user desires to retrieve the copied page, a link to the pointer is activated.
