# Timeouts
# The client_body_timeout and client_header_timeout directives are
# responsible for the time a server will wait for a client body or
# client header to be sent after request. If neither a body or header
# is sent, the server will issue a 408 error or Request time out.
#
# The keepalive_timeout assigns the timeout for keep-alive connections
# with the client. Simply put, Nginx will close connections with the
# client after this period of time.
#
# Finally, the send_timeout is a timeout for transmitting a response
# to the client. If the client does not receive anything within this
# time, then the connection will be closed.
#
#
# send the client a "request timed out" if the body is not loaded
# by this time. Default 60.
#
