Hi,

you can use the following irule as an alternative. It's working perfect on several production environments :

when CLIENT_ACCEPTED {
    set default_pool [LB::server pool]
}

when HTTP_REQUEST {
    if { [active_members $default_pool] < 1 } { 
        HTTP::respond 200 content [ifile get "/Common/maintenance.html"] noserver "Content-Type" "text/html" "Cache-Control" "no-cache, must-revalidate" 
    }
} 

when LB_FAILED { 
    HTTP::respond 200 content [ifile get "/Common/maintenance.html"] noserver "Content-Type" "text/html" "Cache-Control" "no-cache, must-revalidate" 
}

Hi Yann, thanks for the Irule, our requirement is only to show maintenance page if the whole VIP is down i.e. none of the servers are operational.

 

So I guess I will just use the last condition in your iRule?

 

And also, how can we use a logo in the iFile? do I just import a picture directly as an iFile on f5?
