# Relayd DSR support (4.4)

Direct Server Return: traffic does not need to pass the load balancer

We support this with `route to`: Hinges on sloppy state tracking - the load balancer sees only part of the connection

Use with caution

    redirect "www" {
    	 listen on $webserver port http interface $ext_if
    	 route to <webpool> check http "/status.html" code 200
    }
