When user opens a downloaded file, that file should open when it interacts with the server.File what ever we downloaded from server should not open if the user don't have interaction with the server..
Already file get downloaded in to my system. When I opens the file from mu client system, it should contact the server and should get the latest file from server. If the server is down or my internet is down, then my file should not get open. Please provide some inputs....
Please suggest me on this and how can i proceed further.
Thanks in advance,
