client

问题 I have a server that sends my client the address of a backup server in case it goes down. On the server side the backup server is running. On the client side once the connection is lost I am not able to make the client to connect to the backup server. I know that I have to add the connection logic to the following callback in twisted.internet.protcol.Protocol class MyProtocol(Protocol): def connectionLost(self, reason): print 'Connection Lost' print 'Trying to reconnect' # How do I reconnect

问题 I have a feeling I should know this. I have a web app that contains a large number of images, css and script files. The problem I'm having is that if I update the app and one of these 'static' items has changed, I need to ensure that a browser accessing the app is using the newest version of the file.

问题 been trying to figure this problem out for about 5 hours but cant seem to see it, although all the steps are done to send data, I can only receive messages to the server, but not from server to client.
