Abstract

A method of processing, at a web server, a long-polling between a client and a service server configured to provision a service to the client over a network includes: receiving, at the web server, a poll request from the client; transmitting, via the web server, the poll request to the service server; receiving, at the web server, a poll reply to the poll request from the service server; generating, at the web server, webpage data based on the data in the poll reply; and transmitting, via the web server, the webpage data to the client as the poll reply. The poll reply received at the web server includes data to be applied in association with the client.

Claims

1. A method of processing, at a web server, a long-polling between a client and a service server configured to provision a service to the client over a network, the method comprising:

receiving, at the web server, a poll request from the client;

transmitting, via the web server, the poll request to the service server, the poll request comprising a request for maintaining a connection between the web server and the service server;

receiving, at the web server, a normal request different from the poll request from the client;

transmitting, via the web server, the normal request to the service server;

receiving, at the web server, a normal reply to the normal request from the service server;

transmitting, via the web server, the normal reply to the client;

receiving, at the web server, a poll reply to the poll request from the service server, the poll reply comprising data for reflecting a processing result of the service server with respect to the normal request from the client;

generating, at the web server, webpage data based on the data comprised in the poll reply; and

transmitting, via the web server, the webpage data to the client as the poll reply.

2. The method of claim 1, wherein:

the service comprises a game service; and

the webpage data comprises data to configure a game service screen at the client.

3. The method of claim 1, wherein, in response to a standby mode, the service server is configured to delay transmission of the poll reply to the poll request.

4. The method of claim 1, wherein:

the service server is configured to process the normal request to generate the processing result; and

the data in the poll reply received at the web server comprises data to apply the result in association with the client.

5. The method of claim 1, wherein the data in the poll reply received at the web server comprises data used by the service server to control the client.

6. The method of claim 1, further comprising:

receiving, at the web server in response to reception of the poll reply by the client, a retransmission of the poll request from the client; and

transmitting, via the web server, the retransmitted poll request to the service server.

7. A non-transitory computer-readable storage medium comprising one or more sequences of one or more instructions that, in response to being executed, cause at least one apparatus to implement the method of claim 1.

14. The method of claim 3, wherein, in response to generation of data corresponding to the processing result of processing the normal request from the client, the service server is configured to transmit the poll reply to the web server comprising the data corresponding to the processing result.

16. The method of claim 5, wherein, in response to generation of data to control the client in association with the provision of the service to the client, the service server is configured to transmit the poll reply to the web server comprising the data to control the client.

18. The method of claim 6, further comprising:

receiving, at the client, the poll reply comprising the webpage data;

processing, at the client, the webpage data to display a service screen; and

retransmitting, via the client, the poll request to the web server in response to receiving the poll reply.

20. The method of claim 1, further comprising:

installing, while the web server remains in session with the service server, another web server to provision the service in association with the web server and the service server.

8. A long-polling processing system of a web server configured to process a long-polling between a client and a service server configured to provision a service to the client over a network, the long-polling processing system comprising:

at least one processor; and

at least one memory comprising one or more sequences of one or more instructions that, in response to being executed by the at least one processor, cause the long-polling processing system at least to;

control the web server to receive a poll request from the client;

control the web server to transmit the poll request to the service server, the poll request comprising a request for maintaining a connection between the web server and the service server;

control the web server to receive a normal request different from the poll request from the client;

control the web server to transmit the normal request to the service server;

control the web server to receive, from the service server, a normal reply to the normal request;

control the web server to transmit the normal reply to the client;

control the web server to receive a poll reply to the poll request from the service server, the poll reply comprising data for reflecting a processing result of the service server with respect to the normal request from the client;

control the web server to generate webpage data based on the data comprised in the poll reply; and

control the web server to transmit the webpage data to the client as the poll reply.

9. The long-polling processing system of claim 8, wherein:

the service comprises a game service; and

the webpage data comprises data to configure a game service screen at the client.

10. The long-polling processing system of claim 8, wherein, in response to being in a standby mode, the service server is configured to delay transmission of the poll reply to the poll request.

11. The long-polling processing system of claim 8, wherein:

the service server is configured to process the normal request to generate the processing result; and

the data in the poll reply received at the web server comprises data to apply the result in association with the client.

12. The long-polling processing system of claim 8, wherein the data in the poll reply received at the web server comprises data used by the service server to control the client.

13. The long-polling processing system of claim 8, wherein the long-polling processing system is further caused at least to:

control the web server to receive, in response to reception of the poll reply by the client, a retransmission of the poll request from the client; and

control the web server to transmit the retransmitted poll request to the service server.

15. The long-polling processing system of claim 10, wherein, in response to generation of data corresponding to the processing result of processing the normal request from the client, the service server is configured to transmit the poll reply to the web server comprising the data corresponding to the processing result.

17. The long-polling processing system of claim 12, wherein, in response to generation of data to control the client in association with the provision of the service to the client, the service server is configured to transmit the poll reply to the web server comprising the data to control the client.

19. The long-polling processing system of claim 13, wherein the client is configured to:

receive the poll reply comprising the webpage data;

process the webpage data to display a service screen; and

retransmit, in response to reception of the poll reply, the poll request to the web server.
