How do you test?

Note: many (most?) browsers won't keep connections open for such a 
long time and will close them after a minute or so.  E.g. Chrome 
unconditionally closes connections after 5 minutes.

Note well: nginx itself might close keepalive connections before 
timeout passes if it's short on worker_connections.  Though I 
suppose you are hitting browsers behaviour instead.
