This concerns the problem I am facing in making web application. This is what I am going through : There is a server and, clients. As soon as the server gets a request it needs to send a message to n-1 || n clients to update an object. Polling is a solution but inefficient. So, I am finding a solution in which as soon as the server gets to know about the concerned event, all clients are acknowledged about it and to take appropriate action, like reloading the object or doing a local update to the object.
I do have a potential solution known by pubsubhubbub. Checking it out, hope it works.
