  • Request authentication token
    Patent number: 9282088
    Abstract: An authentication mechanism for use in network-based services generates an authentication token. The authentication token is provided to a client device as part of the code comprising a content page. The content page code is received and loaded by a browser application at the client device. When the content page code is received and loaded by the browser application, the authentication token is loaded by the browser as well. Upon receiving subsequent input, the browser application may send a content request to the server. The content request includes the authentication token maintained by the browser application in the content page. A server may validate the authentication token provided in the request using version information and one or more master authentication tokens.
