PROBLEM TO BE SOLVED: To use a URL of a Web server to acquire a resource while making it difficult to cause a problem such as information leakage, etc. at the time of remote access by a reverse proxy server method.SOLUTION: A client terminal, when using a one-time URL with a limited access permitting period to acquire a resource, transmits the one-time URL to a proxy server. The proxy server uses the one-time URL to authenticate access, and uses a normal URL recovered from the one-time URL to transfer the resource from a Web server to the client terminal. The client terminal, when using a normal URL with description of a resource position on the Web server to acquire the resource, transmits a URL with the normal URL added to the previously-transmitted one-time URL. The proxy server uses the one-time URL included in the received URL to authenticate the access, and uses the normal URL included in the URL to transfer the resource from the Web server to the client terminal. |
