The TimeOut directive currently defines the amount of time Apache will
wait for three things:

     1. The total amount of time it takes to receive a GET request.
     2. The amount of time between receipt of TCP packets on a POST or
        PUT request.
     3. The amount of time between ACKs on transmissions of TCP packets
        in responses

i am interested in what the change would be if you wrote a server-side
function, however.
