Applying a health monitor with DNS returned IP address

Hi,

Even if I gave you a solution, I think it is obviously not the best practice. create a pool with pool member is as easy as create a DNS record.

The best solution is still to create pools with same name as host :

tmsh create ltm pool www.company.com monitor tcp members add { www.company.com:443 { fqdn { name www.company.com autopopulate enabled } } } 

then, use the following irule:

when HTTP_REQUEST {
    if {[HTTP::uri] starts_with http} { HTTP::uri [findstr [HTTP::uri] [HTTP::host] [string length [HTTP::host]]} 
    if {[catch {pool [getfield [HTTP::host] ":" 1]}]} {
        HTTP::redirect "https://www.company.com/" 
    }
}
