Intermediate server having control program for storing content accessed during browsing sessions and playback program for asynchronously replaying browsing sessions

摘要

An intermediate server for sharing data between a sender computer and receiver computer(s)is disclosed. A sender initiates a browsing session by (1) requesting a session setup form from the intermediate server that is returned with a beginning URL or (2) being redirected to the intermediate server. A intermediate server control program retrieves content from a server, modifies the hyperlinks within the content by appending the original URL to the URL of the intermediate server, stores the modified content data for later use, and forwards the modified content data to the sender. In asynchronous playback mode, a receiver connects to the intermediate server using a session identifier associated with sender's browsing session. An intermediate server playback program retrieves and pushes the stored content to the receiver. Storing the modified content guarantees that sender and receiver view the same content sequence as opposed to the same URL sequence.
