Abstract

A local client computer includes a local hypertext server, a local application program, and a downloader for downloading a copy of a remote network document (local copy), that is accessible by the local application program, onto the client computer. When connected to the network, a downloader is executed to create the local copy on the client. When disconnected, the local copy may be accessed and modified through the client browser in a manner that is similar to when the client is connected to the network.

Claims

D) a hypertext server coupled with the interceptor for formatting data received from the interceptor into formatted data having a selected interface format, said formatted data including a number of changes to be made in the remote document;

E) a local application program executable by the processor for receiving the formatted data from the hypertext server and effectuating the changes in the local copy of the remote document; and

F) a mechanism for accessing a reconciliation engine in the remote network device to cause the changes in the local copy to be reflected in the remote document on the remote network device.

15. The computer system of claim 14, wherein the local hypertext server comprises:

A) an engine for formatting data received from the interceptor into the formatted data;

B) a directory mapping table for identifying a location of the local copy of the remote document in a directory structure that is substantially similar to a tree structure on the remote network device, the tree structure containing the remote document;

C) a data pump for downloading the remote document from the remote network device; and

D) a cache control for causing the data pump to download the local copy of the remote document from the remote network device to the memory of the computer system.

16. The computer system of claim 14, wherein the interceptor comprises:

A) a redirector for receiving browser requests from the browser and directing specified requests to the local hypertext server; and

B) a connection manager for determining if the computer system is connected to the network.

17. A method of processing a remote document stored in a network device remote from a local computer system, the local computer system having a processor, a memory, and a client browser, and being connectable to the remote network device by a network, the method comprising the steps of:
