PROBLEM TO BE SOLVED: To provide a web service provision apparatus, in which a web service provision apparatus existing in a private network sends an access request message to a web service request apparatus existing outside the private network and then maintains a session with the web service request apparatus, so that the web service request apparatus can receive web services. SOLUTION: The web service provision apparatus includes a message generation unit which generates an access request message including predetermined connection maintaining information, a session management unit which manages the session with the web service request apparatus that receives the access request message and a task processing unit which processes a task according to a task request message from the web service request apparatus, which is received through the session. A load imposed on network bandwidth can be reduced because the web service request apparatus existing outside the private network is connected with the web service provision apparatus existing in the private network and a service is provided while a session between the web service provision apparatus and the web service request apparatus is maintained.
