To display Maintenance Page using iRule

Hi Yasunori,

Can you try this?

when HTTP_REQUEST {
	if { [active_members [LB::server pool ]] < 1 } {
		switch [HTTP::uri]
		{
		  "/application.css" { HTTP::respond 200 content [ifile get "MAINTENANCE_application"] "Content-Type" "text/css" }
		  "/contents.css" { HTTP::respond 200 content [ifile get "MAINTENANCE_contents"] "Content-Type" "text/css" }
		  "/default.css" { HTTP::respond 200 content [ifile get "MAINTENANCE_default"] "Content-Type" "text/css" }
		  "/defaultHub.css" { HTTP::respond 200 content [ifile get "MAINTENANCE_defaultHub"] "Content-Type" "text/css" }
		  "/footer_logo.png" { HTTP::respond 200 content [ifile get "MAINTENANCE_footer_logo"] "Content-Type" "image/png" }
		  "/footer_privacy.png" { HTTP::respond 200 content [ifile get "MAINTENANCE_footer_privacy"] "Content-Type" "image/png" }
		  "/global_navi.css" { HTTP::respond 200 content [ifile get "MAINTENANCE_global_navi"] "Content-Type" "text/css" }
