Redirecting to a webpage when all the health check fails to the memerbs o the pool

I am having the same issue, except I am redirecting many applications across many virtual servers.

 

 

Would it be safe to apply the same logic by using the following code or is there a more effecient way to handle showing a page when the pool members are down?

 

 

when RULE_INIT {
   set down_response "
}
when HTTP_REQUEST {
switch [getfield [string tolower [HTTP::uri]] "/" 2] {
app1 { 
if { [active_members p1] < 1 } {
HTTP::respond $down_response
} else {
pool p1 
}
app2 {
if { [active_members p2] < 1 } {
HTTP::respond $down_response
} else {
pool p2
}
  ...
appN { 
if { [active_members pN] < 1 } {
HTTP::respond $down_response
} else {
pool p1 
}
default { pool p_default }
}
}
