I rule for maintenance page

Hi Shailesh,

Can you try this iRule and look logs?

when HTTP_REQUEST {
	if { [active_members [LB::server pool]] < 1 } {
		log local0. "All members down. URI=[HTTP::uri]"
		switch -glob [string tolower [HTTP::uri]] {
			"*n=197*" { HTTP::redirect "https://d-www.abc.com/system-maintenance" }
			"*nrpp=25*" { HTTP::redirect "http://s-www.xyz.com/maintenance/index.html" }
		}
	}
}
