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.
