Authentication and authorization protocol for secure web-based access to a protected resource

When a user makes a request to access a protected resource identified by a URL, client-side code in a web browser is used to generate an authentication token, which is then sent to the server along with an identity cookie that was set by that server. The authenticated token is then used by the server to authenticate that the request is properly tied to a given identity contained in the identity cookie. If the authentication token can be validated at the server, an access control decision is then executed to determine whether to invoke the request for the protected resource. If the authentication token cannot be validated, an access denied request is returned to the requesting client.
