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.

is there way using http or specific functionality inside browser?

websockets, comet, http long polling.
