A method for improving the availability and reliability of a computer clustering system having first and second servers that are connected to each other by a communication link and that each have an associated mass storage device. In one implementation, the method begins when the first server detects a loss of communication over the communication link from the second server to the first server that prevents the servers from communicating with each other. The first server then analyzes the communication link to determine if the communication link is functioning properly. If the communication link is functioning properly, then the first server continues operation, assuming a right to survive without communicating with the second server or with the mass storage device of the first server or with the mass storage device of the second server, and the first server services network requests that would otherwise be serviced by the second server.

A system that automatically obtains Web page-specific scripts to save and restore the state of a Web page. When a user bookmarks or copies a Web page URL to the clipboard, a function is called to create a page state file that is stored together with the current URL to create a bookmark. When the bookmark is loaded or pasted into the location bar of the Web browser, the system reads the URL and page state file, and loads but does not yet display the Web page indicated by the URL of the bookmark. The system then locates the Restore Page State function in the loaded Web page's script, and executes the Restore Page State function on the page state file, resulting in modification to the DOM (Document Object Model) representation of the Web page and display of the Web page to the user based on the modified DOM.
