Time out (in seconds) before shutting down a proxy that is no longer serving requests.
The proxy Keep-Alive timeout is used to shut down the proxy that hasn't serve any requests during the specified time. The KEEP_ALIVE element specifies how long (in seconds) the proxy waits with no request to process before determining whether to shut down.
If the KEEP_ALIVE entry is missing, the proxy will never shutdown.
<KEEP_ALIVE>10</KEEP_ALIVE>
In this usage example, the proxy timeout is set to 10 seconds.
