In one aspect, this comprises embedding a nonce and a script in all responses from the server to the client wherein, when executed, the script adds the nonce to each request from the client to the server; sending the response with the nonce and the script to the client; and verifying that each request from the client includes the nonce sent by the server from the server to the client. The script preferably modifies all objects, including dynamically generated objects, in a server response that may generate future requests to the server to add the nonce to the requests. The server verifies the nonce value in a request and optionally confirms the request with the client if the value is not the same as the value previously sent by the server. Server-side aspects might be embodied in the server or a proxy between the server and the client. Show less
