Abstract

A server is in communication with a plurality of clients being executed by a host. The server is configured to receive a message from a first client of the plurality of clients. The message indicates that the first client currently has focus, wherein the message is transmitted by the first client with a first cookie. The server is configured to identify that a second client of the plurality of clients utilizes a second cookie that matches the first cookie, wherein the second client is currently receiving data from the server using a low-latency update mechanism. The server is also configured to downgrade the second client from the low-latency update mechanism to a high-latency update mechanism, wherein the high-latency update mechanism is configured to enable the second client to conduct a poll of the server periodically for updates.

Claims

1. A system comprising a server in communication with the plurality of clients, said server being configured to:

receive a message from a first client of the plurality of clients, the message indicating that the first client currently has focus, wherein the message is transmitted by the first client with a first cookie;

identify that a second client of the plurality of clients utilizes a second cookie that matches the first cookie, the second client currently receiving data from said server using a low-latency update mechanism; and

downgrade the second client from the low-latency update mechanism to a high-latency update mechanism, the high-latency update mechanism configured to enable the second client to conduct a poll of said server periodically for updates.

2. The system of claim 1, wherein each of the plurality of clients corresponds to a respective web browser instance.

3. The system of claim 1, wherein said server is further configured to transmit data to the first client using the low-latency update mechanism in response to receiving the message indicating that the first client has focus.

4. The system of claim 3, wherein:

said server is further configured to receive an additional message from a third client of the plurality of clients, the additional message from the third client indicating that the third client currently has focus, and wherein the additional message is transmitted by the third client with a third cookie that matches the first cookie and the second cookie; and

said server is further configured to downgrade the first client from the low-latency update mechanism to a high-latency update mechanism based on the additional message.

5. The system of claim 4, wherein said server is further configured to maintain the second client in the high-latency update mechanism when the first client is downgraded from the low-latency update mechanism to the high latency update mechanism.

6. The system of claim 1, wherein code on said server responsible for the downgrading is abstracted such that underlying code responsible for providing updated data to the clients is unaware of whether the clients are receiving data using the low latency update mechanism or the high latency update mechanism.

7. At least one computer-readable storage medium having computer-executable instructions embodied thereon, wherein, when executed by at least one processor, the computer-executable instructions cause the at least one processor to:

receive a message from a first client of a plurality of clients, the message indicating that the first client currently has focus, wherein the message is transmitted by the first client with a first cookie;

identify that a second client of the plurality of clients utilizes a second cookie that matches the first cookie, the second client currently receiving data using a low-latency update mechanism; and

downgrade the second client from the low-latency update mechanism to a high-latency update mechanism, the high-latency update mechanism configured to enable the second client to conduct a poll periodically for updates.

8. The at least one computer-readable storage medium of claim 7, wherein each of the plurality of clients corresponds to a respective web browser instance.

9. The at least one computer-readable storage medium of claim 7, wherein the computer-executable instructions further cause the at least one processor to transmit data to the first client using the low-latency update mechanism in response to receiving the message indicating that the first client has focus.

10. The at least one computer-readable storage medium of claim 9, wherein the computer-executable instructions further cause the at least one processor to:

receive an additional message from a third client of the plurality of clients, the additional message from the third client indicating that the third client currently has focus, the additional message being transmitted by the third client with a third cookie that matches the first cookie and the second cookie; and

downgrade the first client from the low-latency update mechanism to a high-latency update mechanism based on the additional message.

11. The at least one computer-readable storage medium of claim 10, wherein the computer-executable instructions further cause the at least one processor to maintain the second client in the high-latency update mechanism when the first client is downgraded from the low-latency update mechanism to the high latency update mechanism.

12. The system of claim 7, wherein the computer-executable instructions provides an abstraction layer such that underlying code responsible for providing updated data to the clients is unaware of whether the clients are receiving data using the low latency update mechanism or the high latency update mechanism.

13. A method for transmitting data, said method comprising:

receiving a message from a first client of a plurality of clients, the message indicating that the first client currently has focus, wherein the message is transmitted by the first client with a first cookie;

identifying that a second client of the plurality of clients utilizes a second cookie that matches the first cookie, the second client currently receiving data using a low-latency update mechanism; and

downgrading the second client from the low-latency update mechanism to a high-latency update mechanism, the high-latency update mechanism configured to enable the second client to conduct a poll periodically for updates.

14. The method of claim 13, wherein each of the plurality of clients corresponds to a respective web browser instance.

15. The method of claim 13, further comprising transmitting data to the first client using the low-latency update mechanism in response to receiving the message indicating that the first client has focus.

16. The method claim 15, further comprising:

receiving an additional message from a third client of the plurality of clients, the additional message from the third client indicating that the third client currently has focus, the additional message being transmitted by the third client with a third cookie that matches the first cookie and the second cookie; and

downgrading the first client from the low-latency update mechanism to a high-latency update mechanism based on the additional message.

17. The method of claim 16, further comprising maintaining the second client in the high-latency update mechanism when the first client is downgraded from the low-latency update mechanism to the high latency update mechanism.

18. The method of claim 13, further comprising providing an programming interface to underlying code such that the underlying code responsible for providing updated data to the clients is unaware of whether the clients are receiving data using the low latency update mechanism or the high latency update mechanism.
