Authentication revalidation

1. A system, comprising:

a communication interface configured to:

establish a WebSocket connection with a requester of the connection, wherein an authentication of the requester is configured to expire; and a processor coupled with the communication interface and configured to:

provide a request to provide an update of the authentication to revalidate the authentication, wherein the request is included in a WebSocket frame, the request includes a control byte sequence that has been specifically selected for an authentication revalidation functionality and the control byte sequence indicates that the WebSocket frame is to be interpreted as a control message controlling the authentication revalidation functionality extending a WebSocket protocol of the WebSocket connection rather than a normal message of the WebSocket protocol of the WebSocket connection; and

receive the update of the authentication without disconnecting the WebSocket connection;

wherein a same device establishes the WebSocket connection with the requestor of the WebSocket connection, provides the request to provide the update of the authentication to revalidate the authentication, and receives the update of the authentication.

2. The system of claim 1 , wherein establishing the WebSocket connection includes initializing an extension of a WebSocket protocol of the WebSocket connection at least in part by selecting the control byte sequence specifically for the authentication revalidation functionality and providing the control byte sequence to the requestor of the WebSocket connection.

3. The system of claim 1 , wherein the control byte sequence is included in a payload portion of the WebSocket frame and in the event, content to be included a payload portion of a second WebSocket frame to be sent happens to include the control byte sequence but the authentication revalidation functionality is not desired for the second Websocket frame, an indication to temporarily not interpret the control byte sequence as requesting the authentication revalidation functionality is included the second WebSocket frame.

4. The system of claim 1 , wherein the authentication of the requester is configured to expire at a preconfigured time.

5. The system of claim 1 , wherein the authentication of the requester is configured to expire at a time associated with when the authentication is dynamically revoked.

6. The system of claim 1 , wherein the authentication authorizes the requestor to access a service until the authentication expires.

7. The system of claim 1 , wherein the request is provided at a predetermined amount of time before an expiration time when the authentication is configured to expire.

8. The system of claim 1 , wherein the request is provided via the WebSocket connection.

9. The system of claim 1 , wherein the request identifies a location address where the update should be sent.

10. The system of claim 1 , wherein the update includes an authorization credential extending validity of the authorization.

11. The system of claim 1 , wherein the update is provided via the WebSocket connection.

12. The system of claim 1 , wherein the update is provided via a communication connection separate from the established WebSocket connection.

13. The system of claim 1 , wherein the update is received via an HTTP connection.

14. The system of claim 13 , wherein the update includes a cookie provided via the HTTP connection.

15. The system of claim 1 , wherein the update includes an HTTP “GET” request.

16. The system of claim 1 , wherein the processor is further configured to determine validity of the received update.

17. The system of claim 1 , wherein the communication interface is further configured to provide a response indicating whether the authentication has been successfully revalidated using the update.

18. The system of claim 17 , wherein the response includes an HTTP communication status code.

19. A method, comprising:

using a communication interface to establish a WebSocket connection with a requester of the connection, wherein an authentication of the requester is configured to expire;

providing a request to provide an update of the authentication to revalidate the authentication, wherein the request is included in a WebSocket frame, the request includes a control byte sequence that has been specifically selected for an authentication revalidation functionality and the control byte sequence indicates that the WebSocket frame is to be interpreted as a control message controlling the authentication revalidation functionality extending a WebSocket protocol of the WebSocket connection rather than a normal message of the WebSocket protocol of the WebSocket connection; and

receiving the update of the authentication without disconnecting the WebSocket connection;

wherein a same device establishes the WebSocket connection with the requestor of the WebSocket connection, provides the request to provide the update of the authentication to revalidate the authentication, and receives the update of the authentication.

20. A computer program product, the computer program product being embodied in a tangible computer readable non-transitory storage medium and comprising computer instructions for:

establishing a WebSocket connection with a requester of the connection, wherein an authentication of the requester is configured to expire;

providing a request to provide an update of the authentication to revalidate the authentication, wherein the request is included in a WebSocket frame, the request includes a control byte sequence that has been specifically selected for an authentication revalidation functionality and the control byte sequence indicates that the WebSocket frame is to be interpreted as a control message controlling the authentication revalidation functionality extending a WebSocket protocol of the WebSocket connection rather than a normal message of the WebSocket protocol of the WebSocket connection; and

receiving the update of the authentication without disconnecting the WebSocket connection;

wherein a same device establishes the WebSocket connection with the requestor of the WebSocket connection, provides the request to provide the update of the authentication to revalidate the authentication, and receives the update of the authentication.
