PROBLEM TO BE SOLVED: To provide an apparatus for making a web application highly available, wherein recreation of the web application is made unnecessary when proving off-line functions. SOLUTION: A web application apparatus including a cache 15 for storing the contents of transmission/reception based on user's operation between a browser and a server includes a request/response management unit 16 which manages requests/responses between the browser 10 and the server, determines an on-line state or an off-line state, and in the off-line state, sends a response from the cache instead of the server; a user's operation log management DB 17, which stores and manages a user's operation log acquired by the browser in the off-line state, the contents of a request from the browser to the server and the contents of a response to the request from the cache by the request/response management unit; and an off-line operation reflecting unit 18, which detects that the request/response management unit is turned from the off-line state to the on-line state, reproduces the user's operation from the user's operation log and reflects the reproduced user's operation to the server.
