Is there a difference between long-polling and using Comet?

Some Comet techniques don't require that you constantly open new requests (the chunked hidden iframe, for instance), the idea being to hold the request open and have the server periodically sending data. But this doesn't work well across all major browsers without (as one Wikipedia contributor delicately put it) negative side-effects, hence the long-polling technique. More in the linked article.

As mentioned by Marcelo, Comet is usually used to describe any techniques for "HTTP streaming", including long-polling. In some cases, Comet might also refer more specifically to the Bayeux Protocol. For instance, the jQuery Comet plugin is of this protocol.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
