Please assist me in creating irule

Hi,

you can use following code (not tested)

It retrieve printer name, resolve printer address with DNS servers in pool p_dns, then define as

when HTTP_REQUEST {
    if {[scan [HTTP::uri] {/%[^/]/%[^/]/} corpcode printername] == 2} {
        set printer "${corpcode}-${printername}.lsapps.net"
            HTTP::path [string map "/${corpcode}/${printername}/ /" [HTTP::path]]
            foreach dns [active_members -list p_dns] {   
             Check if the first list element was empty
            if {[set dest [lindex [RESOLV::lookup @[lindex $dns 0] -a $printer] 0]] ne ""} {
                 Set Node IP based on DNS resolution
                node $dest 80
                break
            }
        }
    }
}
