Establishing websocket protocol extensions
A request to upgrade a connection to a WebSocket connection is received. A response that the connection has been upgraded to the WebSocket connection is provided. The WebSocket connection utilizes a WebSocket protocol. An identification of a set of one or more extensions to the WebSocket protocol of the WebSocket connection is received via the WebSocket connection.
1. A system, comprising:
a communication interface configured to:
receive a request to upgrade a connection to a WebSocket connection;
provide a response that the connection has been upgraded to the WebSocket connection, wherein the WebSocket connection utilizes a WebSocket protocol; and
receive via the WebSocket connection, after the response has been received, an identification of a set of one or more extensions to the WebSocket protocol of the WebSocket connection; and a processor coupled with the communication interface.
2. The system of claim 1 , wherein the WebSocket connection is a bi-directional and full-duplex communication channel.
3. The system of claim 1 , wherein the connection requested to be upgraded to the WebSocket connection includes an HTTP connection.
4. The system of claim 1 , wherein the request identifies one or more subprotocols supported by a sender of the request.
5. The system of claim 1 , wherein the request identifies a second set of one or more extensions to the WebSocket protocol.
6. The system of claim 1 , wherein the request identifies a second set of one or more extensions to the WebSocket protocol natively supported by a web browser application.
7. The system of claim 6 , wherein the set of one or more extensions identified by the identifier received via the WebSocket connection is not natively supported by the web browser.
8. The system of claim 1 , wherein the communication interface is further configured to provide a component configured to handle the WebSocket connection.
9. The system of claim 8 , wherein the component includes a software library component at least in part implementing a WebSocket API.
10. The system of claim 8 , wherein providing the component includes inserting program code.
11. The system of claim 8 , wherein the component is preconfigured to request the set of one or more extensions.
12. The system of claim 1 , wherein the communication interface is further configured to provide a second response identifying support for one or more of the extensions in the set of one or more extensions.
13. The system of claim 1 , wherein the communication interface is further configured to provide a second response in response to the received identification and the second response includes an HTTP communication status identifier.
14. The system of claim 1 , wherein the response identifies a first selected subprotocol of the WebSocket connection.
15. The system of claim 14 , wherein the received identification is encoded in the first selected subprotocol.
16. The system of claim 14 , wherein the communication interface is further configured to provide a second response identifying support for one or more of the extensions in the set of one or more extensions and the second response identifies a second selected subprotocol.
17. The system of claim 1 , wherein the received identification is encoded in the WebSocket protocol.
18. The system of claim 1 , wherein the set of one or more extensions is dynamically determined.
19. A method, comprising:
receiving via a communication interface a request to upgrade a connection to a WebSocket connection;
providing a response that the connection has been upgraded to the WebSocket connection, wherein the WebSocket connection utilizes a WebSocket protocol; and
receiving via the WebSocket connection, after the response has been received, an identification of a set of one or more extensions to the WebSocket protocol of the WebSocket connection.
20. A computer program product, the computer program product being embodied in a non-transitory tangible computer readable storage medium and comprising computer instructions for:
receiving a request to upgrade a connection to a WebSocket connection;
providing a response that the connection has been upgraded to the WebSocket connection, wherein the WebSocket connection utilizes a WebSocket protocol; and
receiving via the WebSocket connection, after the response has been received, an identification of a set of one or more extensions to the WebSocket protocol of the WebSocket connection.
