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,

 

To use ifiles, you should upload the html content in plain text in System >> Files

 

Then you need to declare a ifile name in The Local Traffic >> iRules >> iFiles section

 

and finally you can get the content of your ifile using the following command [ifile get MAINTENANCE.html]

 

Note that MAINTENANCE.html is the name of the ifile declaration previously done on Local Traffic >> iRules >> iFiles
