Abstract

Some embodiments of the present invention include a method for controlling requests to be transmitted to a server computing system. The method generating, by a first requester, a request to be transmitted to a first server computing system, the first requester being part of a first group of requesters, each of the requesters in the first group of requesters is configured to access an indicator to determine whether the first server computing system is ready to receive its request, the indicator being set or reset at least based on a response received from the first server computing system, the indicator stored in a memory device associated with a second server computing system; and based on the indicator indicating that the first server computing system is not ready, delaying from transmitting, by the first requester, the request to the first server computing system.

delaying transmission of the request from the first requester to the first server computing system in response to an indication from the indicator that the first server computing system is not ready to receive requests.

2. The method of claim 1, further comprising accessing, by the first requester, the indicator after a delay period to determine whether the second server computing system is ready to receive the request.

3. The method of claim 2, further comprising transmitting, by the first requester, the request to the second server computing system based on the indicator indicating that the second server computing system is ready.

4. The method of claim 3, wherein the indicator is set when the second server computing system is not ready and reset when the second server computing system is ready, wherein the indicator is automatically reset after expiration of a reset period, and wherein the delay period is shorter than the reset period.

5. The method of claim 4, wherein the response received from the second server computing system is configured to include in a response header information to indicate whether the second server computing system ready to accept requests from the requesters in the first group of requesters.

6. The method of claim 5, wherein the first requester is configured to set the indicator based on the response from the second server computing system indicating that the second server computing system is not ready.

7. The method of claim 6, wherein the first requester is configured to reset the indicator based on the response from the second server computing system indicating that the second server computing system is ready.

8. The method of claim 7, wherein the requesters in the first group of the requesters are associated with a first type of service, wherein requesters in a second group of requesters are associated with a second type of service, and wherein a request generated by a second requester in the second group of requesters is configured to be transmitted to the second server computing system without having to access the indicator.

9. The method of claim 8, wherein the second type of service is of higher priority than the first type of service.

10. An apparatus comprising:

one or more processors; and

a non-transitory computer readable medium storing a plurality of instructions, which when executed, cause the one or more processors to;

generate by a first requester of a first group of requesters, a request to be transmitted to a first server computing system;

access, by the first requester of the first group of requesters, an indicator stored in a memory device associated with a second server computing system to verify the availability of first server computing system to receive requests, the indicator being set or reset at least based on a response received from the first server computing system, each requester of the first group of requesters being configured to access the indicator prior to transmitting a request to a second server computing system;

delay transmission of the request from the first requester to the first server computing system in response to an indication from the indicator that the first server computing system is not ready to receive requests.

11. The apparatus of claim 10, further comprising instructions to access the indicator after a delay period to determine whether the second server computing system is ready to receive the request.

12. The apparatus of claim 11, further comprising instructions to transmit the request to the second server computing system based on the indicator indicating that the second server computing system is ready.

13. The apparatus of claim 12, wherein the indicator is set when the second server computing system is not ready and reset when the second server computing system is ready, wherein the indicator is automatically reset after expiration of a reset period, and wherein the delay period is shorter than the reset period.

14. The apparatus of claim 13, wherein the response received from the second server computing system is configured to include in a response header information to indicate whether the second server computing system ready to accept requests from the requesters in the first group of requesters.

15. The apparatus of claim 14, wherein the first requester is configured to set the indicator based on the response from the second server computing system indicating that the second server computing system is not ready.

16. The apparatus of claim 15, wherein the first requester is configured to reset the indicator based on the response from the second server computing system indicating that the second server computing system is ready.

17. The apparatus of claim 16, wherein the requesters in the first group of the requesters are associated with a first type of service, wherein requesters in a second group of requesters are associated with a second type of service, and wherein a request generated by a second requester in the second group of requesters is configured to be transmitted to the second server computing system without having to access the indicator.

18. The apparatus of claim 17, wherein the second type of service is of higher priority than the first type of service.

19. A computer program product comprising a non-transitory computer-readable medium having computer-readable program code embodied therein to be executed by one or more processors, the program code including instructions to:

generate by a first requester of a first group of requesters, a request to be transmitted to a first server computing system;

access, by the first requester of the first group of requesters, an indicator stored in a memory device associated with a second server computing system to verify the availability of first server computing system to receive requests, the indicator being set or reset at least based on a response received from the first server computing system, each requester of the first group of requesters being configured to access the indicator prior to transmitting a request to a second server computing system;
