Web sockets use a lot of resources like comet long polling?

This assumption is totally untrue. See the answer I gave here for more info. It is (for instance) entirely possible to use IAsyncHttpHandler in IIS to perform long-polling, without using a thread per client.

Spender is correct, only shitty web servers (e.g. Apache with mpm_worker or mpm_prefork) use a thread/process per connection.

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.
