iRule for sorry page with pool and path

Silly me. Freestyling iRules is not working out so good it seems. Try this?

    when LB_FAILED {
        LB failed is triggered when the load balancer
        is unable to choose a member for the connection (no available 
        members, or too many retries due to server connection issues

        Set the variable failed to 1 so we can check it later in the response
        set failed 1

        If the client does not request resources in the maintenance
        folder, then rewrite the uri. Otherwise, let it pass through as the 
        content reqests belongs to the maintenance page

        if { !([HTTP::uri starts_with "/maintenance/") } {
            HTTP::uri "/maintenance/maintenance.html"
        }

        Select the pool you want to serve the maintenance page
        pool mov_maintenance_page
    }

    when HTTP_RESPONSE {
        Check if the LB failed event has been triggered by checking if
        the variable failed exists and is set to 1
        if { [info exists failed] && $failed == 1 } {
            Close the connection to make sure that the user makes a new connection
            HTTP::close
        }
    }
