I have a fairly busy server (around a million visitors a day) and until very recently my "Connections: HTTP Used" used to be around 300-500 constantly.
Now though, it is between 0 and 4.
My server is responding fine though and the amount of traffic is the same, just for some reason had a dramatic drop in the amount of http connections used.
Is this correct or some sort of bug?
Req/Second is around 400 still.
The only thing I can remember doing is reducing the Keep-Alive Timeout (secs) by a couple of seconds.
Just curious as to why this would happen?
