network protocols - Is there a way using HTTP to allow the server to update the content in a client browser without client requesting for it? -


it quite easy update interface sending jquery ajax request , updating new content. need more specific.

i want send response client without having requested , update content when have found new on server. no need send ajax request every time. when server has new data sends response every client.

websockets, comet, http long polling.
