Hi

I’m using nginx in front of a long-polling comet app.  
What are the required settings in order to allow a large number of open  
connections?  
For example, what do I need to use for 10k concurrent open connections?

Are there OS settings I need in addition to nginx?  
I’m using ubuntu.

Thanks
