Abstract: Techniques are disclosed relating to a non-blocking token authentication cache. In various embodiments, a server computer system receives a request for service from a client device, with the request including an authentication token issued by an authentication service. The server computer system accesses a cache of previously received validation responses from the authentication service to determine whether one of the validation responses indicates that the authentication token has already been validated by the authentication service. In response to determining that the cache includes a validation response indicating that the authentication token has already been validated by the authentication service, the server computer system first provides a response to the request for service to the client device, and then contacts the authentication service to determine whether the authentication token is still valid.
