ROUTE::expiration
       Returns the remaining time for a route or congestion metrics cache
       entry.

SYNOPSIS
       ROUTE::expiration DESTINATION_IP_ADDRESS (GATEWAY_IP_ADDRESS)?

DESCRIPTION
       Returns the remaining time in seconds. The lifetime of an entry may
       have been set by the route.metrics.timeout sys db variable, the
       cmetrics-cache-timeout TCP profile attribute, or a
       TCP::rt_metrics_timeout iRule.

       The return value only applies to the TMM executing the command. It does
       not consider cache entries on other TMMs.

RETURN VALUE

EXAMPLES
	when CLIENT_CLOSED {
	    # If the entry almost timed out, keep it a little longer next time.
	    set time_remaining [ROUTE::expiration [IP::remote_addr]]
	    if { $time_remaining > 0 && $time_remaining < 100 } {
		 # Default value is 600
		 TCP::rt_metrics_timeout 700
	    }
