Estimating the term…
The invention is to enable a secure sharing of an internet resource with a partner in conversation by the IP telephone, in simple and inexpensive manner and not requiring cumbersome operations, by a communication terminal only, not relying on another equipment. Internet resource sharing means is provided for a shared utilization of a same internet resource (WEB data, FTP file etc.) among the communication terminals (200, 220) in conversation. The sharing of the internet resource is executed by transmitting/receiving URL information of the desired internet resource by FTP or by an E-mail protocol, or by transmitting/receiving the internet resource itself by an HTTP proxy procedure with the partner communication terminal, in which either of the communication terminal and the partner terminal functions as an HTTP proxy server and the other functions as an HTTP client. The sharing of the internet resource can also be achieved by accessing to a server providing a desired internet resource, and changing the transmitting address of the packet transmitted in such operation to an IP address of the partner in conversation, in such a manner that a response packet of the server is transmitted to the partner in conversation.
