Abstract
A method and system for tracking communications in a client-server environment. The method includes the steps of sending a first request from the client to the server over a first connection, sending a first key from the server to the client over the first connection, sending the first key from the client and a second request to the server over a second connection, and sending a response to the second request and a second key distinct from the first key from the server to the client over the second connection. The system includes a client for establishing a terminal connection with a server and a server in communication with the client. The server further includes key generator means generating a plurality of keys for transmission to the client, authentication means in communication with the key generator means receiving the keys from the client to recognize the keys at the server, and discarding means linked to the key generator means for disposing of previously transmitted keys.
