Abstract

A method and system for passing messages to a Web browser. According to one embodiment, a controller receives one or more messages to be delivered to a Web browser session, provides notification to the Web browser session of the receipt of the one or more messages, receives a request by the Web browser session for the one or more messages in response to the notification, the request received via a connection opened by the Web browser session, and delivers the one or more messages to the Web browser session via the connection in response to the request.

Claims

1. A computer-implemented method for passing messages to a Web browser, comprising:

receiving one or more messages to be delivered to a Web browser session;

providing notification to the Web browser session of the receipt of the one or more messages;

receiving a request by the Web browser session for the one or more messages in response to the notification, the request received via a connection opened by the Web browser session; and

delivering the one or more messages to the Web browser session via the connection in response to the request.

2. The method of claim 1, wherein the one or more messages includes a text message.

3. The method of claim 1, wherein the one or more messages includes a byte message.

4. The method of claim 1, wherein the one or more messages includes an object message.

5. The method of claim 1, wherein the one or more messages are placed in a queue before being delivered to the Web browser session.

6. The method of claim 1, wherein the notification to the Web browser session is effected via a polling mechanism.

7. The method of claim 6, wherein the polling mechanism includes changing a value to indicate the receipt of the one or more messages, the value being continually monitored by the Web browser session.

8. The method of claim 7, wherein the value is stored on a server cache.

9. The method of claim 8, wherein the value is a timestamp.

10. The method of claim 1, wherein the request by the Web browser session is an HTTP request.

11. The method of claim 10, wherein the one or more messages are delivered to the Web browser session via a response to the HTTP request.

12. An apparatus for passing messages to a Web browser, comprising:

a processor; and

a memory, coupled to the processor, storing instructions adapted to be executed by the processor to;

receive one or more messages to be delivered to a Web browser session;

provide notification to the Web browser session of the receipt of the one or more messages;

receive a request by the Web browser session for the one or more messages in response to the notification, the request received via a connection opened by the Web browser session; and

deliver the one or more messages to the Web browser session via the connection in response to the request.

13. The apparatus of claim 12, wherein the one or more messages are placed in a queue before being delivered to the Web browser session.

14. The apparatus of claim 12, wherein the notification to the Web browser session is effected via a polling mechanism.

15. The apparatus of claim 14, wherein the polling mechanism includes changing a value to indicate the receipt of the one or more messages, the value being continually monitored by the Web browser session.

16. The apparatus of claim 15, wherein the value is stored on a server cache.

17. The apparatus of claim 16, wherein the value is a timestamp.

18. The apparatus of claim 12, wherein the request by the Web browser session is an HTTP request.

19. The apparatus of claim 18, wherein the one or more messages are delivered to the Web browser session via a response to the HTTP request.

20. A system for passing messages to a Web browser, comprising:

means for receiving one or more messages to be delivered to a Web browser session;

means for providing notification to the Web browser session of the receipt of the one or more messages;

means for receiving a request by the Web browser session for the one or more messages in response to the notification, the request received via a connection opened by the Web browser session; and

means for delivering the one or more messages to the Web browser session via the connection in response to the request.

21. The system of claim 20, wherein the one or more messages are placed in a queue before being delivered to the Web browser session.

22. The system of claim 20, wherein the notification to the Web browser session is effected via a polling mechanism.

23. The system of claim 22, wherein the polling mechanism includes changing a value to indicate the receipt of the one or more messages, the value being continually monitored by the Web browser session.

24. The system of claim 23, wherein the value is stored on a server cache.

25. The system of claim 24, wherein the value is a timestamp.

26. The system of claim 20, wherein the request by the Web browser session is an HTTP request.

27. The system of claim 26, wherein the one or more messages are delivered to the Web browser session via a response to the HTTP request.
