If you want the user who is on your page to get redirected when the file changes on the server then you will not be able to do that using only server-side code. You need to send a message to the client, using eg WebSocket, Socket.io, long polling etc. and the client needs to react to that message and do the actual redirection (ie navigate to some URL).
