Disclosed is a method for synchronizing a file. The method for synchronizing a file comprises the steps of: receiving a first update message from a first terminal connected to a first proxy server, by the first proxy server; transmitting a first synchronization message to at least one second terminal connected to the first proxy server, by the first proxy server; transmitting the first update message to a server, by the first proxy server; transmitting a notification message, which informs that an update is installed for a specific file, to a second proxy server, by the server; transmitting the notification message to at least one third terminal connected to the second proxy server, by the second proxy server; transmitting a second synchronization message to the second proxy server by the server when a predetermined time period has elapsed; and transmitting the second synchronization message to at least one third terminal, by the second proxy server. The method for synchronizing a file according to an embodiment of the present invention further comprises the step of transmitting the second synchronization message to the second proxy server by the server, when the server receives an access message from the second proxy server before the predetermined time period has elapsed. The method of the present invention can significantly reduce traffic due to synchronization by reducing the frequency of the synchronization. |
